Automatically adding header into file with specific extension

[Gundala Viswanath]

Hi,

I want to be able to have VIM automatically
insert this line:

#!/usr/bin/python

Whenever I open a NEW file with *.py or *.egg extension
for example

under bash
$ vi mycode.py

or

$ vi mycode.egg

or under VI

: e mycode.py

Is it possible?
