In the Python programming language, Booleans are data types that can take one of two values: True or False. They are used to represent the result of a logical test, such as whether a condition is met.
For example, the following code checks if the number 10 is even:
"""Returns True if the number is even, False otherwise."""
return number %2 == 0
print(is_even(10)) # True
print(is_even(9)) # False
is_even() takes a number as input and returns a Boolean value. The return statement returns True if the number is even and False if the number is odd.
In the first print statement, is_even() is called with the number 10 as input. Since 10 is even, the function returns True and this value is printed to the console. In the second print statement, is_even() is called with the number 9 as input. Since 9 is odd, the function returns False and this value is printed to the console.
Booleans are used in many other parts of Python, such as conditional statements and loops.
