Accepted answer misses an important point, if you execute etags like find . -type f -name '*.py' | xargs etags then the TAGS file would be generated every time for each file.

The correct way to do it is to append data to the existing TAGS file with --append like

rm -f TAGS
find . -type f -name '*.py' -print0 | xargs -0 etags --append

Also if you want to include identifiers from virtual env site packages dir (e.g.: ~/.virtualenvs/bar/lib/site-packages):

SITEPACKAGES=$(cdvirtualenv;pwd)/lib/python3.6/site-packages/
find $SITEPACKAGES -type f -name '*.py' -print0 | xargs -0 etags -a
