何为死循环？在编程中，一个无法靠自身的控制终止的循环被称为死循环。
python中的死循环
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!'
