Portable Python is a Python installation preconfigured to run from any USB storage device, like a USB stick.
It is available for some versions of Python 2 and Python 3. It also comes with many other Python packages / tools. It is optional to install those during the Portable Python installation. Some of those packages are:
NymPy 1.6.2 (*)
(*) Nympy is probably a typo, it must be Numpy.
The fact that it includes Django, wxPython, PyGTK, PyQt, SciPy, Matplotlib, etc., makes it more useful out of the box.
I am trying out Portable Python and will report on my experience with it after a while. If it works well I think it could be a useful tool for people who sometimes need to program with Python on the go, at any place where they may not have a regular installation of Python available, e.g. if you are somewhere without a desktop PC or a laptop, maybe at an Internet cafe, it could be useful there.
The Portable Python About page gives some info about its background and goals.
