In-depth understanding of Python function parameters

Python is a powerful and flexible programming language that provides many useful features and functions, one of which is function parameters. In Python, function parameters help us pass data to the function so that the function can perform specific operations or return results. This article will delve into the different types and usage of Python function parameters, and provide corresponding source code examples.
