 死循环  这里True,代表1是真,0是假 i = 0 while True:   i = i 1   if i == 50:      print 'I have got to the round 50th!'      continue   if i>70:break   print i  死循环 i = 0 while True:   i = i 1   if i == 5000000:      print 'I have got to the round 50th!'      break #  if i>70:break #  print i 两种方法打印10000000 方法一 i = 0 while i< 10000000:      i = i 1      continue print 'I have got to the round',i #     break #  if i>70:break #  print  方法二: 程序走完才走else,不然不走else i = 0 while i< 10000000:      i = i 1 #     continue else:       print 'I have got to the round',i #     break #  if i>70:break #  print i while和for循环对比(一个道理) i = 0 while i< 10000000:      i = i 1 #     continue else:       print 'I have got to the round',i #     break #  if i>70:break #  print i for i in range(100):     print i else:     print 'The loop is done!'
