Define "working."  Do you mean you get a syntax error when you try to 
run it?  If so, then post the full traceback, which will point to the 
location of the error, (or sometimes the next line or two).

If this is Python 2.x, then you want to derive from object, not just 
make a standalone class.

Have you read the Python tutorial page at:
      http://docs.python.org/2/tutorial/classes.html
That's assuming you're writing for Python 2.7.

python doesn't have instance variables, they're called instance data 
attributes.  Have you defined name as an instance attribute, or a class 
attribute?

Without a colon, this is a syntax error.
And without a body, it's another syntax error.

Where is the parameter to hold the new name?

This references the instance attribute, but doesn't modify it.

No parens, no parameters, no colon.

		return name

ditto
