Certainly seen a huge rise in Python use in private banking sector where I work. The problem is that we get people who aren't devs writing Python code against source DBs, we once had to fight off a trader who fired up some Python code with 150 simultaneous connections to a prod DB, we quickly had to instigate limitations on DB connections for normal users, something we should have done long ago.<p>Our company runs training courses on Python, they're not run by devs or even by the IT dept but by one of the members of the key reporting team, a good Python programmer with plenty of experience in financial modelling but zero IT dev experience. Things are changing.
