29.1 - Functions as First-Class Citizens in Python

In programming languages that treat functions as first-class citizens, functions are treated like any other value, such as integers, strings, or objects. This means that functions can be assigned to variables, passed as arguments to other functions, returned from other functions, and stored in data structures.

Python treats functions as first-class citizens, allowing developers to use them in flexible and expressive ways. This feature enables the use of functional programming concepts and contributes to the versatility of the language.
