parsedatetime.Calendar() is broken in Python 2.7

[bmw]

I've reproduced it on other systems, but on Ubuntu 18.04 with Python 2.7.17:

$ virtualenv -p python2 venv
.Running virtualenv with interpreter /usr/bin/python2
New python executable in /tmp/tmp.QhBu6ZeQC4/venv/bin/python2
 Also creating executable in /tmp/tmp.QhBu6ZeQC4/venv/bin/python
.Installing setuptools, pkg_resources, pip, wheel.../venv/bin/activatedone.
$ . ./venv/bin/activate
$ pip install parsedatetime
DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 is no longer maintained. pip 21.0 will drop support for Python 2.7 in January 2021. More details about Python 2 support in pip, can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support

I'm assuming Python 2.7 is still supported by parsedatetime because I couldn't find anything stating Python 2.7 has been dropped and there is a Python 2 wheel.

I can confirm that I am seeing the same issue:

AttributeError: 'module' object has no attribute 'Locale'

I my case I am seeing it while using csvkit, which is using parsedatetime. I filed an issue there to track the impact https://github.com/wireservice/csvkit/issues/1081.

This is the same bug as #245. The commit that introduced the fault is 18837504778c0dd41ae412bdf86eb81b1be7cdd7.

But.. this is Python 2.7. Most devs would drop support for it as there are only a few months left before it really dies.
