Find version of Modules using PIP : Python Installation manager

Use pip list to list all packages and their versions. You can pipe it to grep to search for the package your interested in:

pip list | grep sympy

Alternatively to get all information about that package including version you can use pip show:

pip show sympy

To upgrade it's simply:

pip install --upgrade sympy

If you need write permissions to your python installation directory don't forget to prepend the pip install command with a sudo: e.g. sudo pip install --upgrade sympy

** With latest Python, you might need to replace pip with pip3 command.
