In this python programming video tutorial you will learn how to loop with index or enumerate function in detail with example. Of course, our list of free python resources should help you learn about it quickly. For Loop. If you’re moving to Python from C or Java, you might be confused by Python’s for loops.

Something like a key, value pair of a dictionary. Both loops in python, while loop and range of len loop perform looping operations over the indexes. Using the range function along with the len() on a list or any collection will give access to the index of each item in the collection. Note that zip with different size lists will stop after the shortest list runs out of items. Both the while loop and range-of-len methods rely on looping over indexes. The working of for loop in Python is different because without requiring the index value we can traverse through a Python list or array.
