I am new in Python. I want to install many 3rd-party libraries (I think they are also called packages?) like, for example, "AstroPy". But I am not sure where the new source code will be stored (I mean, the new ".py" text files that will be downloaded and will contain the Python functions of "AstroPy").

I would like to keep track of all the libraries that I will install. Is there any way to do that for Python?

I used to use IDL and when I want to install a library, I am used to simply download all the text files containing the IDL scripts and then store them in a folder like "/IDL/libraries". That way, I could easily see what I had and also easily uninstall them.

  • Why not use pip, the package manager for Python? It should already be installed along with recent versions of Python, but if not, you can install it as per pip.pypa.io/en/stable/installing – Munir Jan 30 '18 at 23:04

You can find the location of global site-packages (dist-packages that may have been installed via easy_install or pip, a Python package manager) by running:

python -m site

If the package was installed using pip, you can find the location of a specific package (for example, name) by running:

pip show name

Finally, per-user (local) site-packages can be found by running:

python -m site --user-site

You can find slightly more information about dist-packages versus site-packages on the Debian wiki page for Python.
