False

In Python, the False keyword represents a boolean value that indicates the false truth value in logical operations and expressions. It’s defined as a built-in constant with a value of 0 and is a subclass of int.

Python False Keyword Examples

Here’s an example demonstrating how the False keyword can be used in Python:

Python 
>>> is_adult = False
>>> if is_adult:
...     print("They're more than 18 years old")
... else:
...     print("They're less than 18 years old")
...
They're less than 18 years old

In these examples, the conditional check the value of is_adult. Because it’s False, the else clause runs.

Python False Keyword Use Cases

  • Logical operations and comparisons to represent a false truth value
  • Control flow statements like if and while to determine what action to execute
  • Boolean flags in functions to toggle features or options
  • Default argument value in functions and methods
