`True`

In Python, the True keyword represents a Boolean value indicating a truth value in logical operations and expressions. It’s defined as a built-in constant that’s an instance of the bool type, which is a subclass of int, and it has a numeric value of 1.

Python `True` Keyword Examples

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

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

In this example, the conditional checks the value of is_adult. Because it’s True, the if clause runs.

Python `True` Keyword Use Cases

Logical operations and comparisons to indicate a true condition.
Control flow statements like if and while to dictate the execution of code blocks.
Boolean flags in functions to toggle features or options.
Default argument value in functions and methods
