Python's broad range of libraries is very portable over different platforms, such as Unix, Windows, or OS X. These libraries can be easily extended based on your application/program requirement. There is a huge community that works on building these libraries and this makes it the best fit for business use cases.
As far as the Python community is concerned, the Python User Group (PUG) is a community that works on the community-based development model to increase the popularity of Python around the globe. These group members give talks on Python-based frameworks, which help us build large systems.
