What is wrong with this check in the loop?

Question

Python

Here is the code

def get_all_users_First(chat_id_user):
    db.cursor.execute("SELECT chat_user_id FROM users")
    rows = db.cursor.fetchall()
    print(rows)
    for row in rows:
        print(chat_id_user)
        print(row)
        print(rows)
        if chat_id_user == row:
            print('True')
            return True
        else:
            print('false')
            return False

What's wrong? It seems that the first elements are the same, but if still returns False

Answer 1

if chat_id_user == row[0]:

It looks like the first elements are the same

And not identical, and not elements.
1641862320 and ('1641862320',) - what do they have in common? Nothing.
1641862320 - string, ('1641862320') - tuple.
