At my workplace (a large game developer), Python is one of three or four primary languages we use for everything. C++ for the games themselves, C# for UI heavy tools (this is relatively recent, C++ is also still used for a lot of tools), and Python for gluing it all together. (Lua would be the fourth, for in-engine scripting only). In my world, Python replaced Perl as the language of choice for anything in a very broad "miscellaneous" category of tools. Mostly that happened 10 years ago, I haven't seen any Perl in a long, long time. Additionally, as it makes more sense to have web-based tools for certain things, Django has found its way in too. Since Python already has a strong foothold, Django makes a lot more sense in our environment than Rails. I can find a smattering of things in other languages in our code bases, including Ruby and Erlang, but for the most part Python is the language of choice for things that aren't actual game code or Windows tools.
