打破Python中的嵌套（双重）循环

可能不是您想要的，但是通常您需要将After

break

find

True

for word1 in buf1:     find = False     for word2 in buf2:         ...         if res == res1:  print "BINGO " + word1 + ":" + word2  find = True  break  # <-- break here too    if find:         break

另一种方法是使用生成器表达式将squash压缩

for

for word1, word2 in ((w1, w2) for w1 in buf1 for w2 in buf2):    ...     if res == res1:         print "BINGO " + word1 + ":" + word2        break

您也可以考虑使用

itertools.product

from itertools import productfor word1, word2 in product(buf1, buf2):    ...     if res == res1:         print "BINGO " + word1 + ":" + word2        break
