Python help() Function

In this Article we’ll go through the Python help Function and how to use it.

When you download python into your PC, many helpful tools and built-in functions accompany it. One of these helpful features is the python documentation. The Python help() function provides an easy and internet free way to access the documentation for a specific function, keyword, class or module.



If you come across a module or function who’s syntax you’re looking for, or maybe the input parameter’s it takes. Simply type that module or function into the help() function. Fair warning, the documentation of the average module is well over 100 lines.
