The attributes 'agile' and 'name' are giving me errors

When I try to access the 'name' attribute on the Thief class it gives me a AttributeError. This is the code from the play.py file:

from thieves import Thief

isaac = Thief("Isaac", sneaky=False)

print(isaac.name)
print(isaac.sneaky)
print(isaac.agile)
print(isaac.hide(8))

I have no idea why, I've doubled checked all the code and it matches one for one to the teachers code.

Also when I print the agile attribute it prints 'Isaac', the name value. Does anybody have any idea why or what is causing this?

This is the rest of the code

import random
from attributes import Agile, Sneaky
from character import Character

class Thief(Agile, Sneaky, Character):
    def pickpocket(self):
        return self.sneaky and bool(random.randint(0,1))

import random

class Sneaky:
    sneaky = True

    def __init__(self, sneaky=True):
        super().__init__(*args, **kwargs)
        self.sneaky = sneaky

    def hide(self, light_level):
        return self.sneaky and light_level < 10


class Agile:
    agile = True

    def __init__(self, agile=True, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.agile = agile

    def evade(self):
        return self.agile and random.randint(0, 1)

class Character:
    def __init__(self, name="", **kwargs):
        if not name:
            raise ValueError("'name' is required")
        self.name = name
        for key, value in kwargs.items():
            setattr(self, key, value)

Can you post a snapshot? Click the camera icon in the upper right corner, then 'Take Snapshot', then post the link created here.

I'm not using Workspaces I'm using VScode.

You could create a workspace and drag your files to the lower left corner to import.

At the very least, upload the contents of thieves.py

The critical factor is a positional argument will be assigned to the first available parameter regardless if it is a positional or keyword parameter.

Given 

isaac = Thief("Isaac", sneaky=False)

The first parameters seen are from Agile.__init__:

(agile=True, *args **kwargs)

Here, “Isaac” is assigned to agile and sneaky=False is added you the **kwargs dictionary which is passed to Sneaky

The next parameters are from Sneaky.__init__:

(self, sneaky=True)

Here, the sneaky keyword argument matches the sneaky parameter, so it is assigned. This concludes argument to parameter matching.

Note: Sneaky.__init__ does not have an *args or **kwargs parameter so no arguments will ever be passed to Character via the super() statement.

Post back if you need more help. Good luck!!!
