I have a class, robot, in a file called robot.py

I want to create a robot instance in my main script like so:

in robot.py:

```
class robot(object):
    def __init__(self,pygame,screen_width,screen_height):

```

in main.py:

```
import pygame, sys, copy
import mouse
import robot
import menu
import button
from pygame.locals import *
...
size = [1200,900]
my_robot = robot(pygame,size[0]-400,size[1]-100)

```

error:

```
me:cup-robot Me$ python run.py
Traceback (most recent call last):
  File "run.py", line 24, in <module>
    my_robot = robot(pygame,size[0]-400,size[1]-100)
TypeError: 'module' object is not callable

```

how do I do this?
