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?

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

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

Use a threading lock to synchronize access to the session data, preventing race conditions.

Can you provide a code example?

Sure! Here's a simple example:

import threading

sessions = {}
lock = threading.Lock()

def login(user_id):
    with lock:
        # Check credentials and create session
        sessions[user_id] = 'session_data'
