You can also loop through the list items by referring to their index number.

and len() functions to create a suitable iterable.

Print all items by referring to their index number: thislist = ["apple", "banana", "cherry"] for i in range(len(thislist)):

The iterable created in the example above is [0, 1, 2].

You can loop through the list items by using a while loop. Use the len() function to determine the length of the list, then start at 0 and loop your way through the list items by referring to their indexes. Remember to increase the index by 1 after each iteration.

Print all items, using a while loop to go through all the index numbers thislist = ["apple", "banana", "cherry"]
