the best estimate anyone can seem to make of the size of the Python user base is that there are roughly 1 million Python users around the world today (plus or minus a few). This estimate is based on various statistics, like download rates and developer surveys.
Because Python is open source, a more exact count is difficult there are no license registrations to tally. Moreover, Python is automatically included with Linux distributions, Macintosh computers, and some products and hardware, further clouding the user-base picture.
In general, though, Python enjoys a large user base and a very active developer community.
Because Python has been around for some 19 years and has been widely used, it is also very stable and robust.

Probably the only common thread amongst the companies using Python today is that Python is used all over the map, in terms of application domains.
Its general-purpose nature makes it applicable to almost all fields, not just one. In fact, it’s
safe to say that virtually every substantial organization writing software is using Python,
whether for short-term tactical tasks, such as testing and administration, or for long term strategic product development.
Python has proven to work well in both modes.
