How do I check the versions of Python modules?

I installed the Python modules construct and statlib using setuptools: sudo apt-get install python-setuptools sudo easy_install statlib sudo easy_install construct How do I check their versions from the command line?
Use pip instead of easy_install. With pip, list all installed packages and their versions via: pip freeze On most Linux systems, you can pipe this to grep (or findstr on Windows) to find the row for the particular package you're interested in. Linux: pip freeze | grep lxml lxml==2.3 Windows: pip freeze | findstr lxml lxml==2.3 For an individual module, you can try the __version__ attribute. However, there are modules without it: python -c "import requests; print(requests.__version__)" 2.14.2 python -c "import lxml; print(lxml.__version__)" Traceback (most recent call last): File "<string>", line 1, in <module> AttributeError: 'module' object has no attribute '__version__' Lastly, as the commands in your question are prefixed with sudo, it appears you're installing to the global python environment. I strongly advise to take look into Python virtual environment managers, for example virtualenvwrapper.
