如何查看python中安装程序是否登录成功?

Question

我要从c#到Python几天，不知道如何在Python中获得回调函数?

请告诉我如何才能发现登录是否成功，否则给我一个重试下一个密码的机会?

import instaloader
from getpass import getpass
L = instaloader.Instaloader()
USER = input('Enter Instagram Username: ')
PASSWORD = getpass('Enter Password: ')
L.login(USER, PASSWORD)
if (L.Login ??) # how to check if login was successful?
profile = instaloader.Profile.from_username(L.context, USER)
# print follower names for test...
for f in profile.get_followers():
print(f.username)

提示:用python 3.10编写的代码

您可以尝试这样做。当密码错误时，它将继续循环，如果由于无效登录而导致错误，则让该人再次尝试他们的凭据。

import instaloader
from getpass import getpass
L = instaloader.Instaloader()
USER = input('Enter Instagram Username: ')
while True:
try:   
PASSWORD = getpass('Enter Password: ')
L.login(USER, PASSWORD)
break
except:
print("Wrong Password")
