The whileloop requires relevant variables to be ready, in this example we need to define an indexing variable, i, which we set to 1. The break Statement. With the breakstatement we can stop the loop even if the while condition is true: Example. Exit the loop when i is 3: i = 1. while i 6: print(i) if i == 3:
