TypeError: super() argument 1 must be type, not int (Python)

Question

I am trying to create a GroupMessage class that inherits some of its attributes from the main Chat class. I am getting an error at the super(chat_id, user1).__init__() line. I am unable to fix it!

class Chats(object):
    def __init__(self, chat_id, user1):
        self.id = chat_id
        self.initiator = user1
        self.messages = {}  # Key is current date/time; value is a list of messages


class GroupMessage(Chats):
    def __init__(self, chat_id, user1, group_name, message):
        super(chat_id, user1).__init__()
        self.group = group
        self.messages[datetime.datetime.now()] = self.messages[datetime.datetime.now()].append(message)

Upon instantiating GroupMessage, I get an error!

Chat_group = GroupMessage(1, "Batool","AI_group","Text Message")
TypeError: super() argument 1 must be type, not int

You should do instead of super(chat_id, user1).__init__() you should do:

super().__init__(chat_id, user1) # Work in Python 3.6
super(GroupMessage, self).__init__(chat_id, user1) # Work in Python 2.7

or

Chats.__init__(self, chat_id, user1)

This last option is not recommended if exist change that your class hierarchy change in the future. I really don’t like it for others motive but still worth it a mention.
