Something like this I guess?

>>> proc = Popen("cat", shell=True, stdout=open(inname, "w"), stdin=open(outname,"r"))

inname and outname should be appropriate input (existing) and output (to be created) files. ie put the strings directly there or assign to the variables
prior to the Popen call

And BTW 
Two suggestions
1. Read the docs
2. Dont top-post https://en.wikipedia.org/wiki/Posting_style#Top-posting
