Python中断多重循环的思路总结

for i in range(10):

  if i > 5:

    print i

    break

for i in range(10):

  for j in range(10):

    if i+j > 5:

      print i,j

      break

def f():

  flag = 0

  for i in range(10):

    for j in range(i):

      if i+j>5:

        print i,j

        flag = 1

        break

    if flag == 1:

      break

if __name__ == "__main__":

  f()

def work():

  for i in range(10):

    for j in range(10):

      if i+j > 5:

        return i,j

print work()

from itertools import product

for i,j in product(range(10), range(10)):

  if i+j > 5:

    print i,j

    break

class Found(Exception):

  pass

try:

  for i in range(10):

    for j in range(i): #第二重循环跟第一重有关

      if i + j > 5:

        raise Found

except Found:

  print i, j
