How to make a variable in a bot global for only one person?

Question

Python

Hello! Faced the following problem:
I am making a telegram bot that leaves comments on the site.
Using this code:

def desc(message):
    username = message.from_user.username
    idd = message.from_user.id
    msg = message.text
    c.execute("INSERT INTO ads (worker,wid,title) VALUES (%s,%s,%s)",(username,idd,msg))
    link.commit()
    c.execute("SELECT id FROM ads WHERE worker = %s AND wid = %s AND title = %s",(username,idd,msg))
    global ad_id
    ad_id = c.fetchall()[0]['id'];
    msg = bot.send_message(message.chat.id,"Коментарий:")
    bot.register_next_step_handler(msg,price)
def price(message):
    username = message.from_user.username
    idd = message.from_user.id
    msg = message.text
    c.execute("UPDATE ads SET description = %s WHERE id = %s",(msg,ad_id))
    link.commit()
    msg = bot.send_message(message.chat.id,"Теперь цена с копейками (Пример: 7000.00)")
    bot.register_next_step_handler(msg,comision)
def comision(message):
    username = message.from_user.username
    idd = message.from_user.id
    msg = message.text
    c.execute("UPDATE ads SET price = %s WHERE id = %s",(msg,ad_id))
    link.commit()
    msg = bot.send_message(message.chat.id,"На последок комиссию укажи (Пример: 70.00)")
    bot.register_next_step_handler(msg,succes)

The problem is that you need to remember somewhere who writes this comment at all, using a database is stupid in my opinion in this situation, local variables are visible only in the function scope. There is only one way out - to go to the global one, but here again there is a problem, the global variable is created for everyone, that is, if the second user starts writing a comment, he will write it not under his own nickname. In general, everything is somehow bad for me (Please help!

Answer 1

variables are only visible in the scope of the function. There is only one way out - to fuck in the global

Can this variable be passed to register_next_step_handler?
