# Parse information from Linux file to Windows using python

I am trying to parse some contents from my Linux environment and dump them into an excel file in my Windows environment using python.

eg: foo/bar/myfile.txt has some contents I want to stick to an excel file in my windows env C:foo\bar\myfile.txt

I know how to extract the information I need but I cannot find a solution to create a file in my Windows OS from my linux env in python. any little info helps. Thanks!
