"Open with..." a file on Windows, with a python application

Question

I am trying to figure out how to make a python program open a file when a user right clicks on the file and selects "Open With". For example, I want a user to be able right click on a text file and to select my program so that my program can process the text file. Is the name of the text file passed into my program someway? Thanks.

Answer 1

My approach is to use a redirect .bat file containing python someprogram.py %1. The %1 passes the file path into the python script which can be accessed with
from sys import argv argv[1]
