Loop Through a List
You can loop through the list items by using a for loop:
Example
Print all items in the list, one by one:
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.
Example
Print all items by referring to their index number:
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.
Example
thislist = ["apple", "banana", "cherry"]
i = 0
while i < len(thislist):
print(thislist[i])
i = i + 1
Print all items, using a while loop to go through all the index numbers
Looping Using List Comprehension
List Comprehension offers the shortest syntax for looping through lists:
Example
A short hand for loop that will print all items in a list:
thislist = ["apple", "banana", "cherry"]
[print(x) for x in thislist]
