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)

You will learn more about for loops in our Python For Loops Chapter.

Check if Item Exists

To determine if a specified item is present in a list use the in keyword:

Example

Check if "apple" is present in the list:

thislist = ["apple", "banana", "cherry"]

if "apple" in thislist:

 print("Yes, 'apple' is in the fruits list")

List Length

To determine how many items a list has, use the len() method:

Example

Print the number of items in the list:

thislist = ["apple", "banana", "cherry"]

print(len(thislist))

Add Items

To add an item to the end of the list, use the append() method:

Example

Using the append() method to append an item:

thislist = ["apple", "banana", "cherry"]

thislist.append("orange")

print(thislist)
