导语: 本文主要介绍了关于Python里有死循环吗的相关知识,希望可以帮到处于编程学习途中的小伙伴

Python 中有无限循环吗?

什么是无限循环?在编程中,无法在自己的控制下终止的循环称为死循环。

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!'
