Position only argument | Keyword only argument ( Function )
Description:
Welcome to HDR Programming! In this tutorial, we'll explore the concepts of positional-only and keyword-only arguments in Python functions. Python provides flexibility in defining function parameters, allowing you to specify whether arguments must be passed positionally, by keyword, or both. Understanding positional-only and keyword-only arguments is essential for writing clear, robust, and flexible functions in Python.
Overview:
Positional-only arguments are parameters that can only be passed by position and not by keyword, while keyword-only arguments are parameters that can only be passed by keyword and not by position. In this video, we'll delve into the syntax and usage of positional-only and keyword-only arguments, explore their benefits and limitations, and demonstrate how to leverage them effectively in your Python functions.
Topics Covered in this Video:
