无限循环

如果条件判断语句永远为 true,循环将会无限的执行下去,如下实例:

实例

#!/usr/bin/python # -*- coding: UTF-8 -*- var = 1 while var == 1 : # 该条件永远为true,循环将无限执行下去 num = raw_input("Enter a number :") print "You entered: ", num print "Good bye!"

以上实例输出结果:

代码语言:javascript复制
Enter a number  :20
You entered:  20
Enter a number  :29
You entered:  29
Enter a number  :3
You entered:  3
Enter a number between :Traceback (most recent call last):
  File "test.py", line 5, in <module>
    num = raw_input("Enter a number :")
KeyboardInterrupt

注意:以上的无限循环你可以使用 CTRL C 来中断循环。
