I initially installed a version of python-git (GitPython) on my machine. It was version 0.1. Then I used pip to upgrade it to the latest. Now I was looking for the appropriate docs and fell unsure of which version I actually installed. So how to find the version of the installed python package?
Usually a command line like this does it on UNIX:
All eggs live in site-packages folder and they have version number in their folder / .egg file name.
Your question lacks operating system details and what Python was used to install, so it is not possible to give the exact answer.
