Python Packages Tools, with Python 3.3 support

Project description

pkgtools is a Python library that offers some tools to work with Python Packages. It includes two packages:

  • pkgtools.pypi: a simple yet powerful interface to PyPI (Python Package Index)
  • pkgtools.pkg: some package utilities, like metadata reading

Hello World!

['0.5', '0.4', '0.3', '0.2']
>>> pypol_egg = pypi.release_urls('pypol_', '0.5')[2]
