There is a successor project https://github.com/vaeth/replacer Use that instead since it is better in almost every aspect:
When I wrote this code many years ago, python has just been released. There was no python style recommendation out there (or I was not aware of). From current viewpoint the code reads rather ugly and hardly pythonic. However, I left it unchanged except for some python2/3 compatibility quirks.
pyrep (Python grep) is a python script with which you can search
and also replace regular expressions in a collection of files.
Its functionality is similar to the perl script plrep from
https://github.com/vaeth/mv_perl/
To install this script, just copy the content of bin/ into your $PATH.
To get zsh completion, copy the content of zsh/ to your zsh's $fpath,
perhaps /usr/share/zsh/site-functions/.
For Gentoo, there is an ebuild in the mv repository
(available by app-select/eselect-repository or app-portage/layman).
