command00 = input() 
 
if command00 == '!reg': 
    username = input('Your name: ') 
    userpass = input('Your pass: ') 
    cur.execute("INSERT INTO users(name, pass) VALUES(?, ?)", [username, userpass]) 
    con.commit() 
    cur.close() 
    con.close() 
if command00 == '!lin': 
    entername = input('Enter name: ') 
    enterpass = input('Enter pass: ') 
    cur.execute("SELECT pass INTO truepass FROM users WHERE name = entername")
