# break statement in Python

This tutorial will teach you how to use the Python break statement to exit a loop prematurely.

You may want to end a for loop or a while loop early regardless of the results of the conditional tests. In these cases, the break statement can be useful:

`break`

To end a loop when a condition is True, you typically use the break statement in conjunction with the if statement.

## break statement and for loop in Python

The following code demonstrates how to use the break statement within a for loop:

```for index in range(n):
# more code here
if condition:
break```

The break statement terminates the loop instantly if the condition evaluates to True in this syntax. The remaining iterations will not be completed.

In this example, the break statement is used within a for loop:

```for index in range(0, 10):
print(index)
if index == 3:
break```

Output

0 1 2 3

How does it work?

The for loop iterates through ten numbers ranging from 0 to 9 and shows each one on the screen.
When the loop number is 3, however, the break statement ends the loop instantly. As a result, the application only displays 4 digits on the screen, ranging from 0 to 3.
In a nested loop, the break statement terminates the innermost loop. As an example:

```for x in range(5):
for y in range(5):
# terminate the innermost loop
if y > 1:
break
# show coordinates on the screen
print(f"({x},{y})")```

Output

(0,0) (0,1) (1,0) (1,1) (2,0) (2,1) (3,0) (3,1) (4,0) (4,1)

Two for loops are used in this example to display the coordinates from (0,0) to (5,5) on the screen.

When y is bigger than one, the break statement in the nested loop terminates the innermost loop.

As a result, you can only observe coordinates with y values of zero and one.

## break statement with while loop in Python

The following example demonstrates how to utilise the break statement within a while loop:

```while condition:
# more code
if condition:
break```

The break statement is used inside a while loop in the following example.

It will ask you to choose your preferred colour. When you type quit:, the software will terminate.

```print('-- Help: type quit to exit --')
while True:
color = input('Enter your favorite color:')
if color.lower() == 'quit':
break```

Output

```-- Help: type quit to exit --
