While Loop

Prev Post

Loops:

Python has two primitive loop commands:

  • while loops

  • for loops

1. While Loops:

In while loop, we can execute block of statements as long as while condition is true.

#Print i as long as i is less than 6:
i = 1
while i <= 5:           
    print(i)           
    i += 1

Output:     
1
2
3
4
5

break Statement

With the break statement we can stop the loop even if the while condition is true:

#Exit the loop when i is 3:
i = 1
while i < 6:   
    print(i)   
    if i == 3:    
        break   i += 1

Output:     
1
2
3

The continue Statement

With the continue statement we can stop the current iteration, and continue with the next:

#Continue to the next iteration if i is 3:
i = 0
while i < 6:   
    i += 1   
    if i == 3:     
        continue   
    print(i)

Output:     
1
