A new release of PyRun, the open source, one-file, no installation version of Python. has just been released by eGenix.

PyRun makes the distribution of a Python interpreter to run scripts and applications to Unix based systems as simple as copying a single file.

Compared to a regular Python installation of typically 100MB on disk, its executable needs 13MB for Python 3 and 11MB for Python 2 and can be compressed to just 3-4MB using the executable packer upx, if needed. This makes it useful for applications and scripts that need to be distributed to several target machines, client installations or customers.

The advantages using PyRun, its features and how to use it are outlined in this EuroPython 2012 talk by  Marc-André Lemburg, CEO of eGenix.com:

The latest release is a patch level release of PyRun 2.0 which added Python 3.4 support. The main changes from 2.0.0 to 2.0.1 is that it has been upgraded to work with Python 2.7.8 by default and a bug in the license printer has been fixed to show the correct license URL.

Thanks to a shell script, install-pyrun, an eGenix PyRun installation is as simple as running:

./install-pyrun targetdir

This will automatically detect the platform, download and install the right pyrun version into targetdir. This script has been  updated to default to eGenix PyRun 2.0.1 and its feature set for this release.
