This is the uncertainties Python package, which performs transparent calculations with uncertainties (aka "error propagation"). This package also calculates derivatives.

GitHub

The master branch is for Python 2.7+ (including Python 3+ through 2to3), while the master_python2.3 branch is for Python 2.3 to 2.6 (with unit tests only run with Python 2.6).

Other master* branches in the Github repository are bleeding-edge, but they are working versions that passed the tests for many versions of Python starting at 2.4.

Other branches might be present in the GitHub repository, but they are temporary and represent work in progress that does not necessarily run properly yet.
