Listing Installed Python Packages

Here is a quick two liner bit of code to see what Python packages you have installed.  I am running this from the command line. Here is the example:

>>> import pip
>>> print sorted(["%s==%s" % (i.key, i.version) for i in pip.get_installed_distributions()])
['arcrest==2.0.100', 'astroid==1.3.2', 'boto==2.38.0', 'cffi==1.1.0', 'colorama=
=0.3.3', 'cryptography==0.9', 'enum34==1.0.4', 'idna==2.0', 'ipaddress==1.0.7',
'libarchive==0.4.3', 'logilab-common==0.63.2', 'matplotlib==1.3.0', 'nose==1.3.6
', 'numpy==1.7.1', 'pip==7.0.0', 'pyasn1==0.1.7', 'pycparser==2.13', 'pylint==1.
4.0', 'pylzma==0.4.6', 'pyopenssl==0.15.1', 'pyparsing==1.5.7', 'pyzillow==0.4.0
', 'setuptools==17.0', 'six==1.9.0', 'wheel==0.24.0']

Enjoy!

I normally just do "pip freeze", which gives the same result. Are there additional options available when doing it this way?
