Python break

The break keyword in Python is used to exit a loop immediately. It’s commonly used to stop looping early based on a condition or to exit infinite loops.

Syntax

Here is the syntax for using break in while loop:

while condition:
  if some_condition:
    break  # Exit the loop

Here is the syntax for using break in for loop:

for item in iterable:
  if some_condition:
    break  # Exit the loop

Parameters:

• The break statement does not take any parameters.

Return value:

The break statement does not return any value. It simply exits the nearest enclosing loop immediately.

Example: Exiting a Loop Early Using break

This example iterates through a list of numbers and stops printing when the number 58 is reached, demonstrating how break exits the loop immediately:

numbers = [14, 25, 36, 47, 58, 69, 70]
for number in numbers:
  print(number)

  if number == 58:
    break
