Real Python - How to Write Pythonic Loops

You can use these techniques to refactor your existing Python for loops and while loops in order to make them easier to read and more maintainable. You'll learn how to use Python's range(), xrange(), and enumerate() built-ins to refactor your loops and how to avoid having to keep track of loop indexes manually.
The main takeaways in this tutorial are that:
Writing C-style loops in Python is considered not Pythonic. Avoid managing loop indexes and stop conditions manually if possible.
Python's for loops are really "for each" loops that can iterate over items from a container or sequence directly.
