Break

Introduction:

  • The break statement in Python is used to exit a loop prematurely, even before the loop condition becomes false.

Syntax:

python
break
  • Just the break keyword on a line by itself.

Examples:

  1. Break Statement with While Loop:

    • This example uses a while loop to print numbers from 1 to 10. The loop breaks when the number 4 is reached.

      python
      i = 1
while i <= 10:
    if i == 4:
        break
    print(i)
    i += 1

    • Output:

      1
2
3
  2. Break Statement with For Loop and Range:

    • Using a for loop with range to break the loop when about to print the number 4.

      python
      for x in range(1, 11):
    if x == 4:
        break
    print(x)

    • Output:

      1
2
3

Exercises:

  1. Break While Loop:

    • Write a while loop to print numbers from 1 to 10. Break the loop if the number is 6.

      python
      i = 1
while i <= 10:
    if i == 6:
        break
    print(i)
    i += 1
  2. Break For Loop with Range:

    • Write a for loop to print numbers from 1 to 15. Break the loop if the number is 8.

      python
      for x in range(1, 16):
    if x == 8:
        break
    print(x)

Summary:

  • In this tutorial, we learned how to use the break statement to end a loop execution prematurely, with the help of example programs. Practice using the break statement in different looping scenarios to understand its functionality and use it effectively in your Python programs!
