Boolean values in Python are represented by the keywords True and False. They are essential for controlling the flow of logic in your programs. Booleans are often used in conditional statements and loops.

is_active = True
is_authenticated = False

Logical operations can be performed on Boolean values using and, or, and not. These operations help combine or invert Boolean expressions.

is_logged_in = True
has_permission = False
can_access = is_logged_in and has_permission

You can also use comparison operators to generate Boolean results. For example, ==, !=, >, <, >=, and <= are commonly used.

num1 = 10
num2 = 20
is_equal = (num1 == num2)
is_greater = (num1 > num2)

In Python, the following values are considered Falsy (evaluating to False): None, 0, 0.0, '' (empty string), [] (empty list), and {} (empty dictionary). Everything else is considered Truthy.

value = []
if value:
    print('This is a Truthy value')
else:
    print('This is a Falsy value')

You can convert other types to Boolean using the bool() function. This can be particularly useful when you need to evaluate the truthiness of a value.

check_value = bool('Hello')  # This will be True
check_empty = bool('')  # This will be False

It’s essential to understand how to use Boolean values effectively, especially when working with control flow constructs like if statements and while loops.

age = 18
if age >= 18:
    print('Adult')
else:
    print('Minor')
