Bank of America was supposed to have gotten heavily into Python a couple of years (or more) ago. I had blogged about it here at the time:

and Niall O'Connor from the bank (who spoke at PyCon IE 2013 - http://python.ie/pycon/2013/speakers/niall_oconnor/ ) confirmed via a comment on my post, that they were not "beginning" to do it, but that it had "already happened".
Edit: The reddit thread quoted by the parent comment, also mentions BoA and Niall.
