In Python, a Boolean is a data type that has only two values: True or False.
x = True
y = False
print(type(x)) # <class 'bool'>
print(5 > 3) # True
print(10 == 2) # False
Simple words me: Boolean helps Python decide things like yes/no or true/false in programs.

A Boolean is a built-in data type in Python.

It has only two possible values:

True
False

Internally, Booleans are a subclass of integers:

True → 1
False → 0

print(type(True))   # <class 'bool'>
print(True == 1)    # True
print(False == 0)   # True

Creating Boolean Values

You can create Booleans directly:

is_active = True
is_logged_in = False

Or using the bool() constructor:

print(bool(1))      # True
print(bool(0))      # False
print(bool("Hi"))   # True (non-empty string)
print(bool(""))     # False (empty string)
print(bool([]))     # False (empty list)
print(bool([1]))    # True (non-empty list)

Truthy and Falsy Values

In Python, not just True/False, but values can be evaluated as Boolean:

Falsy values (treated as False):
- 0, 0.0, 0j (numeric zero)
- "" (empty string)
- [] (empty list)
- {} (empty dict)
- set(), tuple()
- None
- False itself
Everything else is Truthy (treated as True).

Boolean Operators

and → True if both operands are True.
or → True if at least one operand is True.
not → negates the value.

x = True
y = False

print(x and y)   # False
print(x or y)    # True
print(not x)     # False

Booleans in Conditions

Booleans are widely used in if statements and loops:

is_admin = True
if is_admin:
    print("Access granted")
else:
    print("Access denied")

Booleans with Comparisons

Comparison operators return Boolean values:

print(5 > 2)    # True
print(10 == 5)  # False
print(4 <= 4)   # True

Summary

bool type has two values: True and False.
Python treats many values as truthy or falsy.
Used in conditions, loops, comparisons.
True = 1, False = 0 (but don’t confuse them with integers in logic).
