The next step in your programming journey involves understanding 'booleans', a fundamental concept in all of computer programming.

Booleans are a type of data that can only be one of two values: true or false. Think of booleans as yes-or-no switches that you use to control the behavior of a program.

For example, if raining is true then we'll need to make sure we wear our coats.

What are Booleans?

Booleans represent the idea of truth and falsity within a program. In Python, the two boolean values are written as True and False.

Creating a Boolean

Here's how you express true or false in Python:

print(True)  # This is the boolean value for "true" 
print(False)  # This is the boolean value for "false"

You simply write either true or false.

It's important to note that in Python, these are case-sensitive, so they must start with an uppercase letter.

Why Booleans Matter

Booleans are crucial because they let you control the flow of your programs. For instance, you can execute a block of code only if certain conditions are met. This is done using "if statements," which rely heavily on booleans. Booleans are also essential in loops, which run repeatedly until a boolean condition is no longer true.
