Python Booleans

In Python, booleans are a data type that represent truth values. There are two boolean values: True and False. Booleans are often used in programming to make decisions and control the flow of a program.

Boolean values can be assigned to variables or used directly in expressions. Here are some examples:

python

x = True
y = False

print(x)  # Output: True
print(y)  # Output: False

# Boolean expressions
print(5 > 3)     # Output: True
print(10 == 10)  # Output: True
print(7 < 2)     # Output: False

# Boolean operators
print(True and False)   # Output: False
print(True or False)    # Output: True
print(not True)         # Output: False

In addition to True and False, Python has a concept of “truthy” and “falsy” values. In boolean contexts (e.g., if statements or while loops), certain values are treated as equivalent to True or False. Here are some examples of truthy and falsy values:

Truthy values:

• Non-zero numbers (e.g., 1, 3.14)
• Non-empty strings (e.g., “hello”)
• Non-empty lists, tuples, sets, or dictionaries
• Functions and classes

Falsy values:

• Zero (0)
• Empty strings (e.g., “”)
• Empty lists, tuples, sets, or dictionaries
• None

You can use truthy and falsy values in conditional statements. For example:

python

x = 10

if x:
    print("x is truthy")
else:
    print("x is falsy")

# Output: x is truthy

In this example, since x has a non-zero value, it is considered truthy, so the code inside the if statement executes.
