Python里有死循环吗

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!'
