python实现无限循环的实例代码

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!"

class Infinit:
    def __iter__(self):
        return self
    def __next__(self):
        return None
for i in Infinit():
    print("好嗨哟,你是不是学会了Python的无限循环!")
print("我是永远不会执行到的")
