To celebrate the release of Python 3.7.3 on 25th March 2019, and with under nine months left for Python 2, here’s some statistics showing how much different Python versions have been used over the past three years.
Here’s the pip installs for all packages from the Python Package Index (PyPI), between January 2016 and March 2019:
The package installer
Python 2 and 3 compatibility library
Scientific computing library
Code coverage testing
2D plotting library
Interface to Last.fm
Statistics were collected using pypi-trends.py, a wrapper around pypinfo to fetch all monthly downloads from the PyPI database on Google BigQuery and save them as JSON files. Data was downloaded over several days as getting all months uses up a lot of free BigQuery quota. Then jsons2csv.py plots a chart using matplotlib. Raw JSON data is in the repo.

- Python version share over time, 2 (January 2016 — October 2018)
- Python version share over time, 3 (January 2016 — December 2018)
