Tips : How to break from nested loops.

break makes you get out of the loop even before the end of the iteration. But, in case of nested loop(multi-layered loop) break only can take you out of the nearest loop.

Now, you can break nested loop with boolean-typed variables which indicates breaking or not to the outer loop.

This is an example of mutiplication tables.

# You need to set breaker variable for boolean to break outer loop.

breaker = False

for i in range(1, 10, 1):
    for j in range(1, 10, 1):
        if i > 2:
            breaker = True				# set breaker True
            break
        print(i , '*', j, '=', i*j)
    if breaker == True:					# check breaker
        break
