Python Booleans

Booleans in Python represent the truth values True and False.

1. Boolean Values

Python has two built-in boolean values: True and False.

x = True
y = False

2. Boolean Operations

Python supports various boolean operations, including and, or, and not.

a = True
b = False

result_and = a and b      # False
result_or = a or b        # True
result_not = not a        # False

3. Comparison Operators

Comparison operators in Python return boolean values based on the comparison of two operands.

x = 5
y = 10

result_equal = x == y        # False
result_not_equal = x != y    # True
result_greater = x > y       # False
result_less = x < y          # True
result_greater_equal = x >= y    # False
result_less_equal = x <= y       # True

4. Boolean Conversion

Many values in Python can be evaluated as boolean expressions. For example, any non-zero number or non-empty container is considered True.

x = 0
y = 10
z = []

result_x = bool(x)      # False
result_y = bool(y)      # True
result_z = bool(z)      # False

Conclusion

Booleans are essential in Python for making decisions and controlling the flow of programs. Understanding boolean operations and comparison operators is crucial for writing effective Python code.
