如您所见，我可以在此处存储密码。 我必须添加一个可以注册新用户的功能。如何做到这一点，以便在创建新用户时可以创建新实例？
import datetime
import getpass
class User:
def __init__(self, username, mail, date_of_birth, gender, password):
self.username = username
self.mail = mail
self.date_of_birth = datetime.datetime.strptime(date_of_birth, "%d.%m.%Y").date()
self.gender = gender
self.password = password
def get_username(self):
return self.username
def get_mail(self):
return self.mail
def get_date_of_birth(self):
return self.date_of_birth
def get_gender(self):
return self.gender
def get_password(self):
self.password
def get_date(self):
return self.date_of_birth
log = ""
def tries_left(self):
max_tries = 3
trie = 0
while trie <= max_tries:
print("wrong password!")
print("tries left " + str(max_tries - trie + 1))
trie +=1
pwrd = input("input password")
if pwrd != self.password:
pass
else:
self.login_or_register()
def login2(self):
global log
log = input("input your username: ")
if log == self.username:
pwrd = input("whats your password?")
if pwrd == self.password:
print("Logged in!")
self.add_password_orCheck_password()
else:
self.tries_left()
else:
print("wrong username!")
self.login2()
def login_or_register(self):
user_input = input("Login or Register: ")
if user_input == "login":
self.login2()
elif user_input == "register":
pass
else:
print("Try again!")
self.login_or_register()
def add_password(self):

def check_passwords(self):

for Site in passwords:

Matt = User("Matterson", "matt@gmail.com", "21.12.1999" ,"male", "Password987")
session1 = Matt.login_or_register()
答案 0 :(得分：1)
我不认为这是一个更好的选择：
users = {}
while True:
name = input('yourtexthere')
email = input('yourtexthere')
year = input('yourtexthere')
gender = input('yourtexthere')
password = input('yourtexthere') # here you will use getpass
users[f'{name}'] = User(name, email, year, gender, password)
但是您也可以将它们存储在列表中，但是随后您将不得不通过索引访问它们，并且您可能希望使用电子邮件作为密钥：
users[f'{email}'] = User(name, email, year, gender, password)
答案 1 :(得分：0)
这是代码（请参阅我的评论），它不是最干净的代码，但是可以工作，在这里您可以尝试实现User类，并根据需要进行创建，但是您需要tkinter的经验（这仅仅是一个例子）希望能对您有所帮助（它还会在此codes目录中创建json文件（如果尚未创建））（并且我希望这样做不会违反某些准则）：
