It's here mostly as a historical relic. If you want a compiled binary (on Linux) you can install it with conda (ideally in its own conda environment): conda install -c davidmertz python=0.9 Skip Montanaro has created a GitHub repository of Python 0.9.1 source.

  • Download Python Sources

    Download Python Sources For most Unix systems, you must download and compile the source code (see the latest releases). The same source code archive can also be used to build the Windows and Mac versions, and is the starting point for ports to all other platforms. You can browse the sources online through the repository viewer. If you want to help with the Python Project, see the Python Developer's Guide.
