How to break out of multiple loops?

Question

Given the following code (that doesn\'t work):

while True:
    #snip: print out current state
    while True:
        ok = get_input(\"Is this ok? (y/n)\")
          


        

Answer 1

There is no way to do this from a language level. Some languages have a goto others have a break that takes an argument, python does not.

The best options are:

1. Set a flag which is checked by the outer loop, or set the outer loops condition.

2. Put the loop in a function and use return to break out of all the loops at once.

3. Reformulate your logic.

Using Function

def doMywork(data):
    for i in data:
       for e in i:
         return 

Using flag

is_break = False
for i in data:
   if is_break:
      break # outer loop break
   for e in i:
      is_break = True
      break # inner loop break
