Find all packages installed with easy_install/pip?

Is there a way to find all Python PyPI packages that were installed with easy_install or pip? I mean, excluding everything that was/is installed with the distributions tools (in this case apt-get on Debian).

pip freeze will output a list of installed packages and their versions. It also allows you to write those packages to a file that can later be used to set up a new environment.

As of version 1.3 of pip you can now use pip list

It has some useful options including the ability to show outdated packages. Here's the documentation: https://pip.pypa.io/en/latest/reference/pip_list/
