Python In Practice - 15 Projects to Master Python - help( )

The video tutorial explains how to use the help function in Python to obtain information about various objects, including built-in modules and custom functions. It demonstrates using the help function with the string class, complex class, and random module. The tutorial also covers defining custom functions and using docstrings to provide detailed help messages for these functions. By incorporating docstrings, users can enhance the clarity and usefulness of help messages for their own functions.
