PyPI is the Python Package Index at http://pypi.python.org/
PyPI has a new home at <http://pypi.python.org/>. Users should need not need to change anything, as the old “www” address should still work. Use of the new address in preference is encouraged.
Developers interested in how PyPI works, or in contributing to the project, should visit http://wiki.python.org/moin/CheeseShopDev
