How can I rewrite python __version__ with git?

Question

I would like to define a __version__ variable in my module which should be automatically updated on git commit similarly to what SVN keywords do. Is there a way

Another possibility other than Versioneer is setuptools_scm.

I have successfully implemented something very similar to the OP by adding the following to setup.py (or by modifying it accordingly):

from setuptools import setup
setup(
    ...,
    use_scm_version=True,
    setup_requires=['setuptools_scm'],
    ...,
)

and, in order to have __version__ updated automatically, added this to __init__.py of my package:

from pkg_resources import get_distribution, DistributionNotFound
try:
    __version__ = get_distribution(__name__).version
except DistributionNotFound:
    # package is not installed
    pass
