User Defined Function in Python Python for Beginners

User-defined functions in Python are custom functions created by users to perform specific tasks or operations. These functions allow developers to modularize their code by encapsulating reusable logic into named blocks.

To define a user-defined function, you use the def keyword followed by the function name and parentheses containing any parameters the function may accept. The function body, which consists of the code to be executed when the function is called, is indented below the function definition.
User-defined functions can also return values using the return statement. This allows functions to produce output that can be used elsewhere in the code.
Overall, user-defined functions are a powerful feature of Python that promote code reusability, readability, and maintainability by allowing developers to encapsulate logic into modular components.
