How to Loop Through a List in Python

If you want to work with every item in a Python list, you usually use a loop.

This page shows the main ways to loop through a list in Python:

Read each item one by one
Print or use each value
Get both the index and the value
Choose the simplest loop for your task

Quick answer

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

for item in items:
    print(item)

Output:

apple
banana
cherry

Use a for loop when you want to process each item in a list one by one.

What this page helps you do

Loop through every item in a list
Print or use each value
Get the item position with enumerate()

Loop through a list with a for loop

This is the most common and beginner-friendly way.

When you write for item in items, Python gives you one list item at a time.
The variable item holds the current value in each loop.

Use this when you only need each value.

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

for item in items:
    print(item)

Output:

apple
banana
cherry

How it works

items is the list
item is a temporary variable
The loop runs once for each value in the list

You can also do other work inside the loop:

prices = [10, 20, 30]

for price in prices:
    print(price * 2)

Output:

20
40
60

If you are new to loops, see Python for loops explained.

Get both index and value with enumerate()

Use enumerate() when you need both:

the position of the item
the item itself

This is better than creating your own counter in most cases.

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

for index, item in enumerate(items):
    print(index, item)

Output:

0 apple
1 banana
2 cherry

This is useful for numbered output:

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

for index, item in enumerate(items):
    print(f"{index}: {item}")

Output:

0: apple
1: banana
2: cherry

Why `enumerate()` is useful

It keeps your code shorter
It avoids manual counters
It makes it clear that you need both index and value

If you want to learn more, read Python enumerate() function explained.

Loop through a list with range() and indexes

Use range(len(my_list)) when you need to work with positions directly.

This style is useful when you want to update list items by index.

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

for index in range(len(items)):
    print(index, items[index])

Output:

0 apple
1 banana
2 cherry

When this approach helps

This pattern is common when changing values in the original list:

numbers = [1, 2, 3]

for index in range(len(numbers)):
    numbers[index] = numbers[index] * 10

print(numbers)

Output:

[10, 20, 30]

Why not use it for everything?

For simple reading, this is less readable than:

for item in items:
    print(item)

So use range(len(...)) only when you really need index access.

If needed, you can also read Python range() function explained and how to get the length of a list in Python.

Loop through a list with a while loop

A while loop gives you more control, but you must manage the index yourself.

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

index = 0

while index < len(items):
    print(items[index])
    index += 1

Output:

apple
banana
cherry

Important

In a while loop, you must increase the index yourself:

index += 1

If you forget this, the loop may never end.

Use a while loop only when you need extra control over:

the index
the stopping condition
more complex loop logic

For most list loops, a for loop is simpler and safer.

When to use each approach

Choose the loop style based on what you need:

Use `for item in my_list`

Use this for most tasks.

for item in items:
    print(item)

Best when:

You only need each value
You want the clearest code

Use `enumerate()`

Use this when you need both index and value.

for index, item in enumerate(items):
    print(index, item)

Best when:

You want the position and the value
You need numbered output

Use `range(len(my_list))`

Use this when you need to work with positions directly.

for index in range(len(items)):
    items[index] = items[index].upper()

Best when:

You need to change items by index
You need direct index access

Use `while`

Use this only when the logic needs manual control.

index = 0
while index < len(items):
    print(items[index])
    index += 1

Best when:

You need custom stopping logic
You need full control over the index

Common mistakes

Here are some common beginner mistakes when looping through lists.

Changing the loop variable does not change the original list item

This code does not update the list:

numbers = [1, 2, 3]

for num in numbers:
    num = num * 10

print(numbers)

Output:

[1, 2, 3]

The variable num only holds a value for the current loop.
It does not replace the item inside the list.

To change the real list items, use indexes:

numbers = [1, 2, 3]

for index in range(len(numbers)):
    numbers[index] = numbers[index] * 10

print(numbers)

Output:

[10, 20, 30]

Using `range(my_list)` instead of `range(len(my_list))`

This is wrong:

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

for index in range(items):
    print(index)

range() needs a number, not a list.

Use this instead:

for index in range(len(items)):
    print(index)

Forgetting to increase the index in a while loop

This causes a problem:

items = ["apple", "banana", "cherry"]
index = 0

while index < len(items):
    print(items[index])

The value of index never changes, so the loop keeps running.

Fix it like this:

items = ["apple", "banana", "cherry"]
index = 0

while index < len(items):
    print(items[index])
    index += 1

Mixing up items and indexes

This code is a common mistake:

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

for item in items:
    print(items[item])

Here, item is "apple", "banana", and "cherry".
Those are values, not index numbers.

If you need indexes too, use enumerate():

for index, item in enumerate(items):
    print(index, item)

FAQ

What is the easiest way to loop through a list in Python?

Use a for loop:

for item in my_list:
    print(item)

It is the simplest and most common option.

How do I get the index while looping through a list?

Use enumerate(). It gives you both the index and the value in each loop.

for index, item in enumerate(my_list):
    print(index, item)

Should I use while or for to loop through a list?

Use for in most cases.

Use while only when you need manual control over the index or stopping condition.

Can I change list items while looping?

Yes, but you usually need indexes.

A loop with range(len(my_list)) is often used for that:

numbers = [1, 2, 3]

for index in range(len(numbers)):
    numbers[index] += 1

print(numbers)

Output:

[2, 3, 4]
