Python In Practice - 15 Projects to Master Python - iter( ) and next( )

The video tutorial explains how to use iterators and the next function in Python. It begins by introducing the concept of iterators and how they can be used to retrieve elements from an iterable. The tutorial then demonstrates creating a list and using it to show iteration without a for loop. The next function is highlighted as a tool to access elements sequentially. Finally, the video discusses practical applications, especially in user-defined classes, where iterators and the next function can be beneficial.
