Python – Loop Lists

Loop Through a List

You can loop through the list items by using a for loop:

thislist = ["apple", "banana", "cherry"]
for x in thislist:
  print(x)

Loop Through the Index Numbers

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

Use the range() and len() functions to create a suitable iterable.

thislist = ["apple", "banana", "cherry"]
for i in range(len(thislist)):
  print(thislist[i])

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

Using a While Loop

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.

thislist = ["apple", "banana", "cherry"]
i = 0
while i < len(thislist):
  print(thislist[i])
  i = i + 1

Looping Using List Comprehension

List Comprehension offers the shortest syntax for looping through lists:

thislist = ["apple", "banana", "cherry"]
[print(x) for x in thislist]
