Loop Through a List
You can loop through the list items by using a for loop:
Example
thislist = ["apple", "banana", "cherry"]
for x in thislist:
print(x)Learn more about for loops in our Python For Loops Chapter.
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.
Example
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.
