I can implement the error function, erf, myself, but I'd prefer not to. Is there a python package with no external dependencies that contains an implementation of this function? I have found http://pylab.sourceforge.net/packages/included_functions.html>this but this seems to be part of some much larger package (and it's not even clear which one!).

I'm sorry if this is a naive question - I'm totally new to Python.
