The Easiest Way to Learn MicroPython – Lessons 6 - For Loops
iPhone How-To by TheiPhoneAppReview.com

Welcome back for Lesson Lessons 6 – For Loops

In our Lesson 5 we reviewed Conditional Statements available in MicroPython programming. This is a critical topic for anyone who wants to direct the flow of their program based on various variable-determined conditions. And prior to that we learned in Lesson 4 the key elements of calculating that would ultimately lead to decision making, Arithmetic and Logical Operat0rs.

Now in Lesson 6 we introduce you to For Loops. One of the most use structures in programming. We delve into the process by which you get a program to repeat a path through your code based on arithmetic or boolean values to get just the result you expect.

MicroPython For Loops

Learning Objectives:

Understand what a for loop is and how to use it in Python.
Be able to write for loops to iterate over lists, strings, and other iterable objects.
Be able to use for loops to perform repetitive tasks.

Introduction

A for loop is a type of control flow statement in Python that allows you to iterate over a sequence of items. This means that you can use a for loop to execute a block of code repeatedly, once for each item in the sequence.

For loops are one of the most important and widely used control flow statements in Python. They can be used to perform a wide variety of tasks, such as:

Printing all the items in a list
Adding up the numbers in a list
Finding the largest or smallest number in a list
Checking if a value exists in a list
Reversing the order of a list

Syntax

The basic syntax for a for loop in Python is as follows:

for <variable> in <iterable>:
  # Code block to be executed for each item in the iterable

Use code with caution. Learn more

The <variable> is a placeholder for the current item in the iterable. The <iterable> is any object that can be iterated over, such as a list, string, or tuple.

Examples

The following example shows how to use a for loop to print all the items in a list:

my_list = ["apple", "banana", "cherry"]
for fruit in my_list:
  print(fruit)

Use code with caution. Learn more

Output:

apple
banana
cherry

The following example shows how to use a for loop to add up the numbers in a list:

my_list = [1, 2, 3, 4, 5]
sum = 0
for number in my_list:
  sum += number
print(sum)

Use code with caution. Learn more

Output:

Nested For Loops

You can also nest for loops inside of other for loops. This can be useful for performing more complex tasks.

For example, the following example shows how to use a nested for loop to print a multiplication table:

for x in range(1, 11):
  for y in range(1, 11):
    print(x * y)

Use code with caution. Learn more

Output:

1 2 3 4 5 6 7 8 9 10
2 4 6 8 10 12 14 16 18 20
3 6 9 12 15 18 21 24 27 30
4 8 12 16 20 24 28 32 36 40
5 10 15 20 25 30 35 40 45 50
6 12 18 24 30 36 42 48 54 60
7 14 21 28 35 42 49 56 63 70
8 16 24 32 40 48 56 64 72 80
9 18 27 36 45 54 63 72 81 90
10 20 30 40 50 60 70 80 90 100

Conclusion

For loops are a powerful tool for performing repetitive tasks in Python. By understanding how to use for loops, you can write more efficient and concise code.

Additional Exercises

Here are some additional exercises to help you practice using for loops in Python:

Write a for loop to print all the vowels in a string.
Write a for loop to find the largest number in a list.
Write a for loop to reverse the order of a list.
Write a for loop to check if a value exists in a list.
Write a for loop to remove all the duplicate items from a list.

Hopefully this lesson has helped you to understand how to use for loops in Python. If you have any questions, please feel free to ask.

Conclusion

So as you can see For loops are one of the most important control flow statements in Python. They allow you to iterate over a sequence of items, executing a block of code for each item in the sequence.

For loops are essential for writing efficient and concise Python code. They can be used to perform a wide variety of tasks, such as:

Processing large amounts of data
Automating repetitive tasks
Implementing algorithms
Building complex data structures

Here are some specific examples of how for loops are used in Python programming:

Data processing: For loops can be used to process large amounts of data, such as reading and writing files, filtering data, and performing calculations on data.
Automation: For loops can be used to automate repetitive tasks, such as sending emails, generating reports, and performing backups.
Algorithm implementation: For loops are used to implement many common algorithms, such as sorting, searching, and traversing data structures.
Data structure construction: For loops can be used to build complex data structures, such as linked lists, trees, and graphs.

Overall, for loops are an essential tool for any Python programmer. By mastering the use of for loops, you can write more efficient, concise, and powerful Python code.

The Easiest Way to Learn MicroPython – Lessons 5 – Conditional Statements
iPhone How-To by TheiPhoneAppReview.com

Welcome back for Lesson Lessons 5 – Conditional Statements

In our introduction we reviewed the most popular IDEs available for MicroPython programming. Then in Lessons 2 & 3 we walked you through coding and running your first program as well as introducing variable and data types. That was followed by Lesson 4 where we went over key elements of calculating that would ultimately lead to decision making, Arithmetic and Logical Operat0rs.

With all of that under your belt you and now ready to instruct the computer to do that decision making for you. These decisions are the foundation of every computer program that does anything even remotely interesting. Without Conditional Statements your program would always yield the same result. And how useless and boring would that be!

In today’s lesson we delve into the process by which you get a program take a specific path through your code to get just the result you expect. Today we cover Conditional Statements.

MicroPython Conditional Statements

MicroPython provides a wide range of conditional operators that can be used to perform decisions based the value of some variable or a comparison of one or more variables. That decision would, presumably lead to a branching of the program that is appropriate to that value or comparison test.

What are conditional statements?

Conditional statements allow you to control the flow of your program based on certain conditions. For example, you can use a conditional statement to check if a number is even or odd, or if a user has entered a valid password.

The if statement

The if statement is the most basic conditional statement in Python. It allows you to check if a condition is true, and then execute a block of code if it is. The syntax for the if statement is as follows:

Python

if condition:

# Code to execute if the condition is true

Use code with caution. Learn more

The condition can be any Boolean expression, such as a comparison between two numbers or a check for the existence of a variable. If the condition evaluates to True, the code block inside the if statement will be executed. Otherwise, the code block will be skipped.

Example:

Python

age = 18

if age >= 18:

print(“You are an adult.”)

else:

print(“You are not an adult.”)

Use code with caution. Learn more

Output:

“You are an adult.”

The else statement

The else statement is used to execute a block of code if the condition in an if statement evaluates to False. The syntax for the else statement is as follows:

Python

if condition:

# Code to execute if the condition is true

else:

# Code to execute if the condition is false

Use code with caution. Learn more

In the previous example, if the user’s age is less than 18, the code block inside the else statement will be executed, and the program will print the message “You are not an adult.”

The elif statement

The elif statement allows you to check multiple conditions in a single if statement. The syntax for the elif statement is as follows:

Python

if condition1:

# Code to execute if condition1 is true

elif condition2:

# Code to execute if condition1 is false and condition2 is true

elif condition3:

# Code to execute if condition1 and condition2 are false and condition3 is true

…

else:

# Code to execute if all conditions are false

Use code with caution. Learn more

The elif statements are checked in order, and the first elif statement with a true condition will be executed. If none of the elif statements have a true condition, the code block inside the else statement will be executed.

Example:

Python

grade = “A”

if grade == “A”:

print(“Excellent!”)

elif grade == “B”:

print(“Good!”)

elif grade == “C”:

print(“Average!”)

elif grade == “D”:

print(“Passing!”)

else:

print(“Failing!”)

Use code with caution. Learn more

Output:

“Excellent!”

Nested if statements

Nested if statements allow you to check multiple conditions in a hierarchical order. The syntax for nested if statements is the same as for regular if statements, but you can have multiple if statements nested inside of each other.

Example:

Python

age = 18

country = “United States”

if age >= 18:

if country == “United States”:

print(“You are eligible to vote in the United States.”)

else:

print(“You are eligible to vote in your country.”)

else:

print(“You are not eligible to vote yet.”)

Use code with caution. Learn more

Output:

“You are eligible to vote in the United States.”

Conclusion

Conditional statements are a powerful tool that allows you to control the flow of your program based on certain conditions. Python has a variety of conditional statements available, including the if, elif, and else statements. You can also nest if statements to create even more complex conditional logic.

By understanding how to use conditional statements, you can write Python programs that can make decisions and respond to different situations.

And of course…Happy coding!

The Easiest Way to Learn MicroPython – Lessons 4 - Arithmetic and Logical Operators

September 12th, 2023

The Easiest Way to Learn MicroPython - Lesson 4 - Arithmetic and Logical Operators
iPhone How-To by TheiPhoneAppReview.com

Welcome back for Lesson 4 - Arithmetic and Logical Operators

In our introduction we reviewed the most popular IDEs available for MicroPython programming. Then in Lessons 2 & 3 we walked you through coding and running your first program as well as introducing variable and data types.

Today we deeper into what really makes a program take one of, typically many, paths to get just the result you expect. Today we cover Arithmetic and Logical Operators.

MicroPython Arithmetic and Logical Operators

MicroPython provides a wide range of arithmetic and logical operators that can be used to perform mathematical and logical operations on data.

Arithmetic Operators

Arithmetic operators are used to perform mathematical operations on numbers. The following table lists the arithmetic operators available in MicroPython:

Operator	Description	Example
`+`	Addition	`1 + 2 = 3`
`-`	Subtraction	`5 - 3 = 2`
`*`	Multiplication	`2 * 3 = 6`
`/`	Division	`6 / 2 = 3`
`//`	Floor division	`10 // 3 = 3`
`%`	Modulus (remainder)	`10 % 3 = 1`

Logical Operators

Logical operators are used to combine two or more conditions and produce a single Boolean result (true or false). The following table lists the logical operators available in MicroPython:

Operator	Description	Example
`and`	Returns true if both conditions are true	`True and True = True`
`or`	Returns true if either condition is true	`True or False = True`
`not`	Inverses the truth value of a condition	`not True = False`

Examples

The following code shows some examples of how to use arithmetic and logical operators in MicroPython:

# Arithmetic operators
print(1 + 2)  # 3
print(5 - 3)  # 2
print(2 * 3)  # 6
print(6 / 2)  # 3.0
print(10 // 3)  # 3
print(10 % 3)  # 1
# Logical operators
print(True and True)  # True
print(True or False)  # True
print(not True)  # False

Using Arithmetic and Logical Operators in MicroPython Programs

Arithmetic and logical operators can be used in MicroPython programs in a variety of ways. For example, you can use them to:

Perform mathematical calculations on data, such as calculating the average of a list of numbers or the distance between two points.
Control the flow of your program using conditional statements and loops.
Make decisions based on the results of logical operations.

Here are some examples of how to use arithmetic and logical operators in MicroPython programs:

# Calculate the average of a list of numbers
numbers = [1, 2, 3, 4, 5]
average = sum(numbers) / len(numbers)
print(average)  # 3.0
# Control the flow of a program using conditional statements
number = 10
if number > 5:
  print("The number is greater than 5.")
else:
  print("The number is less than or equal to 5.")
# Make decisions based on the results of logical operations
is_raining = True
is_cold = False
if is_raining and is_cold:
  print("It is raining and cold outside. Bring an umbrella and a jacket!")
elif is_raining or is_cold:
  print("It is either raining or cold outside. Bring an umbrella or a jacket.")
else:
  print("It is not raining or cold outside. Enjoy the weather!")

Arithmetic Operators

Addition

# Add two numbers
a = 10
b = 20
c = a + b
print(c

Output:

Explanation:

The + operator is used to add two numbers. In this example, we are adding the numbers a and b and storing the result in the variable c.

Subtraction

# Subtract two numbers
a = 10
b = 20
c = a - b
print(c)

Output:

-10

Explanation:

The - operator is used to subtract two numbers. In this example, we are subtracting the number b from the number a and storing the result in the variable c.

Multiplication

# Multiply two numbers
a = 10
b = 20
c = a * b
print(c)

Output:

Explanation:

The * operator is used to multiply two numbers. In this example, we are multiplying the numbers a and b and storing the result in the variable c.

Division

# Divide two numbers
a = 10
b = 20
c = a / b
print(c)

Output:

0.5

Explanation:

The / operator is used to divide two numbers. In this example, we are dividing the number a by the number b and storing the result in the variable c.

Floor Division

# Perform floor division on two numbers
a = 10
b = 20
c = a // b
print(c)

Output:

Explanation:

The // operator is used to perform floor division on two numbers. Floor division is a type of division that returns the largest integer that is less than or equal to the result of the division. In this example, we are performing floor division on the numbers a and b and storing the result in the variable c.

Modulus

# Calculate the modulus of two numbers
a = 10
b = 20
c = a % b
print(c)

Output:

Explanation:

The % operator is used to calculate the modulus of two numbers. The modulus is the remainder of the division of two numbers. In this example, we are calculating the modulus of the numbers a and b and storing the result in the variable c.

Logical Operators

And

# Check if two conditions are both true
condition_1 = True
condition_2 = False
result = condition_1 and condition_2
print(result)

Output:

False

Explanation:

The and operator returns true if both of its operands are true, and false otherwise. In this example, we are checking if the conditions condition_1 and condition_2 are both true. Since condition_2 is false, the result of the and operation is false.

Or

# Check if either of two conditions is true
condition_1 = True
condition_2 = False
result = condition_1 or condition_2
print(result)

Output:

True

Explanation:

The or operator returns true if either of its operands is true, and false otherwise. In this example, we are checking if either of the conditions condition_1 or condition_2 is true. Since condition_1 is true, the result of the or operation is true.

Not

# Reverse the truth value of a condition
condition = True
result = not condition
print(result)

Output:

False

Explanation:

The not operator reverses the truth value of its operand. In this example, we are reversing the truth value of the condition condition. Since condition is true, the result of the not operation is false.

Conclusion

Arithmetic and logical operators are essential tools for any MicroPython programmer. By understanding how to use these operators, you can write more powerful and flexible programs.

I hope this tutorial has been helpful. If you have any questions about arithmetic or logical operators in MicroPython, please feel free to leave a comment below.

And of course…Happy coding!

The Easiest Way to Learn MicroPython - Lessons 2 & 3

August 13th, 2023

Jimbo

The Easiest Way to Learn MicroPython - Lesson 1
iPhone How-To by TheiPhoneAppReview.com

Thanks for sticking with us on this journey to learn how to program the inexpensive Raspberry PI Pico using MicroPython.

We’ve already covered quite a bit of foundational info so if you’re just joining us please review the two previous posts in this series: The Easiest Way to Learn MicroPython - Prep Setup, and The Easiest Way to Learn MicroPython - Lesson 1.

Today, in Lessons 2 & 3, we will cover writing your first Python program and learning about variables and data types. All programming uses a variety of data types and understanding them, and knowing which ones to use when, is critical to being a good programmer.

Lesson 2: Your First Program

Our first foray into actual coding is pretty simple, just the traditional “Hello World!” program.

Type the following code in Thonny’s editor:

print(“Hello, World!”)

Then press Run or Fn + F5 to execute it. You should see Hello, World! in the Shell at the bottom.

This is a simple program that prints a text string. The print() function is used to output information to the console at the bottom of the editor.

OK, that was easy. Let’s move on to Lesson 3: Variables and Data Types

Lesson 3: Variables and Data Types

Goal: Learn about variables and basic data types (strings, integers, and floats)

I. Introduction to Variables

A variable is like a container or a box that you can store a value in. Once a value is assigned to a variable, you can refer to it by the variable’s name, modify it, or use it in operations.

Basic variable assignment:

x = 5

Here, x is the variable and 5 is the value being stored in it.

Example:

Type the following code in Thonny’s editor:

# This is a string

message = “Hello, MicroPython!”

print(message)

# These are integers

x = 10

y = 20

print(x + y)

# This is a float (a number with a decimal point)

pi = 3.14

print(pi)

In this lesson, we define variables using the = sign. A variable can be a string (text), integer (whole number), or float (number with a decimal point). We then print these variables.

II. Data Types

Every value in Python has a datatype. Since everything is an object in Python programming, data types are actually classes, and the variables are instances (objects) of these classes.

1. Integers (`int`)

These are whole numbers (no decimal point). They can be positive, negative, or zero.

my_integer = 7

2. Floats (`float`)

Floating-point numbers (with a decimal point).

my_float = 7.5

note that the numbers 7 and 7.0 are not the same, why not? While they have the same value, 7 is an integer and 7.0 is a float.

3. Strings (`str`)

Textual data, enclosed within single (' ') or double (" ") quotes.

my_string = “Hello World!”

4. Booleans (`bool`)

Values that can only be True or False.

is_sunny = True

5. List

Ordered and changeable collections. Lists are created by placing a comma-separated sequence of items inside square brackets [].

my_list = [1, 2, 3, “apple”, “banana”]

6. Tuple

Ordered and unchangeable (immutable) collections. Tuples are created by placing a comma-separated sequence of items inside parentheses ().

my_tuple = (1, 2, 3, “apple”, “banana”)

7. Dictionary (`dict`)

Unordered, changeable, and indexed collections. They have keys and values. Dictionaries are created by placing items inside curly braces {}.

my_dict = {

“name”: “John”,

“age”: 30,

“is_student”: True

8. Set

Unordered and unindexed collections with no duplicate values. Sets are created by placing a comma-separated sequence of items inside curly braces {}.

my_set = {1, 2, 3, “apple”, “banana”}

III. Determining the Type of a Variable

You can determine the type of a variable using the type() function.

x = 5

print(type(x)) #Output: <class ‘int’>

IV. Type Conversion

Sometimes, you may want to change the type of a variable. This is known as type casting.

int() - converts to integer
float() - converts to float
str() - converts to string

y = 3.14

print(int(y)) #Output: 3

V. Summary

This lesson provides a foundational understanding of variables and data types in Python. As a new programmer, you’ll get more comfortable with these concepts through practice, and they will serve as building blocks for more advanced programming topics.

Variables are named containers for storing values.
Python has several built-in data types, such as integers, floats, strings, booleans, lists, tuples, sets, and dictionaries.
You can check the type of a variable using the type() function.
It’s possible to convert between types, but be cautious about potential data loss or errors.

VI. Exercises

Create a variable name containing your name as a string, and another variable age containing your age as an integer. Print their types.
Convert the age variable into a float, and print its type.
Create a list hobbies containing at least three of your hobbies. Print it out.
Create a dictionary profile containing keys for name, age, and hobbies from the above variables. Print it out.
