Practical Data Science using Python - Python User-Defined Functions

The video tutorial explains the concept of user defined functions in Python, highlighting their importance in code reuse and maintainability. It covers the syntax, including the use of the 'def' statement, input arguments, and the ability to return multiple values. The tutorial also introduces docstrings for documentation and discusses the scope of variables, distinguishing between global and local scopes.
