     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!'
