How can I implement user login in a multithreaded Python application?

How can I implement user login in a multithreaded Python application?

You can use the threading module to handle multiple user logins. Start by creating a login function that checks user credentials.

What if I want to store user sessions after they log in?

You can use a dictionary to store user sessions, where the key is the username and the value is the session data.

How do I ensure thread safety when accessing the session data?

You can use a Lock from the threading module to ensure that only one thread can access the session data at a time.

Can you provide a code example for this?

Sure! Here's a simple example:

import threading

class UserSession:
    def __init__(self):
        self.sessions = {}
        self.lock = threading.Lock()

    def login(self, username):
        with self.lock:
            self.sessions[username] = 'session_data'
            print(f'{username} logged in.')

session_manager = UserSession()
# Create threads for multiple users logging in
