python装饰器的问题
# 装饰器实现登入loggin_status=False
list=[]
def loggin(func):
if loggin_status == False:
def loggin_in():
user=input('user:')
passwd=input('password:')
with open('账号信息','r',) as file:
for i in file.readlines():
list.append(i.strip('\n'))
pass
if list.count(user) is not 0 and list.count(passwd) is not 0:
print('login.............')
global loggin_status
loggin_status=True
else:
print('err')
return loggin_in
@loggin
def shouji():
print('this pages is shouji')
@loggin
def dianqi(list):
print('this pages is dianqi')
while True:
print('''
欢迎使用
1.手机
2.电气
3.退出
''')
a=int(input('>>'))
if a in range(1,4):
if a==1:
shouji()
if loggin_status is False:
print('loggin_status为False')
else:
print('loggin_status为Ture')
elif a==2:
dianqi()
elif a==3:
break
else:
print('不再范围内....')
以上代码本意是想实现，选择后判断是否登入如果登入了就不需要再一次登入，如果没有登入则执行装饰器登入。但是没有实现，请大神指点一下！
以下为执行后的结果：

loggin_status = False

# list.append(i.strip('\n'))
# pass
# if list.count(user) is not 0 and list.count(passwd) is not 0:
