An alternative is to use a special comment, for example:

class MyClass:
     def __init__(self, a, b, c):
         #> a, b, c

And then use, say, a Python script to expand it to:

class MyClass:
     def __init__(self, a, b, c):
         #> a, b, c
         self.a = a
         self.b = b
         self.c = c
         #<

The Python script could be called from the editor.

If you want to add or remove an argument, edit the comment and then run 
the script again. (Hopefully it'll be smart enough to make the necessary 
changes).
