# 3 Simple Examples of For Loop in Python

In this short post, you’ll see 3 simple examples of For Loop in Python:

• Looping over a list
• Looping across multiple lists

## 3 Examples

### Example 1: Looping over a List

Suppose that you created a list of integers:

`my_list = [22, 57, 15, 8, 29]`

To increase each value in the list by 1 using a For Loop:

`my_list = [22, 57, 15, 8, 29]sum_list = []for i in my_list:    sum_list.append(i + 1)print(sum_list)`

You’ll now see that each value in the list increased by 1:

``[23, 58, 16, 9, 30]``

### Example 2: Adding a Break

Assume that you now have the following list:

`my_list = ["red", "red", "red", "red", "blue", "blue", "yellow", "blue", "blue"]`

To add a break once the color is equal to “yellow”:

`my_list = ["red", "red", "red", "red", "blue", "blue", "yellow", "blue", "blue"]new_list = []for i in my_list:    new_list.append(i)    if i == "yellow":        breakprint(new_list)`

You’ll notice that the “yellow” color is the last color in the list:

``['red', 'red', 'red', 'red', 'blue', 'blue', 'yellow']``

### Example 3: Looping Across Multiple Lists

Now assume that you have the following two lists that contain integers:

`list_x = [12, 8, 6]list_y = [2, 3, 4]`

You can then multiply the values across the two lists:

`list_x = [12, 8, 6]list_y = [2, 3, 4]mul_list = []for x in list_x:    for y in list_y:        mul_list.append(x * y)print(mul_list)`

Here is the result:

``[24, 36, 48, 16, 24, 32, 12, 18, 24]``
