Are there any methods for automatically finding which Python versions are supported by packages on PIP?
I am looking for something that generates a table like the one below obtained automatically from the PIP index. A manually mantained table from well-known GitHub repositories and contributors from the community would also be helpful:
2.7.x 3.x
foo ✓ ✗
bar ✓ ✓
baz ✗ ✓
Has anyone compiled a table like this before? Any thoughts on how I could automatically get this information?

Python 2.7 (last version in 2. x ) is no longer under development and in 2020 will be discontinued. Python 3 is a newer version of the Python programming language which was released in December 2008. This version was mainly released to fix problems that exist in Python 2.
In python 2. x, “print” is treated as a statement and python 3. x explicitly treats “print” as a function. This means we need to pass the items inside your print to the function parentheses in the standard way otherwise you will get a syntax error.
If you want to determine whether Python2 or Python3 is running, you can check the major version with this sys. version_info. major . 2 means Python2, and 3 means Python3.
The Python Software Foundation declared Python 2 End of Life (EOL) on January 1, 2020, and ended support. Python 2.7. 18 was the final release of Python 2, released in April 2020.
Just use this: https://pypi.python.org/pypi/caniusepython3/
For the sake of statistics, this is openstack list of deps (161 in total): https://github.com/openstack/requirements/blob/master/global-requirements.txt
And this is what's holding them back:
giampaolo@UX32VD:/tmp$ caniusepython3 -r requirements.txt
