bookBreak and Continue with Nested Loops

You still can use break and continue statements inside the nested loops. But the execution depends on the statement's position in code. Thus, if you use break inside the inner loop, after executing it you leave the inner loop only, but continue to execute commands inside the outer one.

for i in range(10):
  print('Outer loop starts!')
  for j in range(10):
    print(i, j)
    if i==j:
      print('Leaving inner loop')
      break
  print('Outer loop is over!')
copy

The same about continue: you'll go back to the beginning of the inner loop.

Infinite Nested Loops

As you may guess, if one of the loops in infinite, no matter it is outer or inner one, the whole program is infinite, too. Remember to double-check the process and stop conditions for each loop.

Tarefa

Is everything okay with the given code? Ware the infinite program execution!

  • Think about which loop causes the infinite execution.
  • Modify the code to make it valid and finite.
