import os import sys import math import tempfile import argparse import subprocess
On Unix, os, sys, and math are mostly wrappers around libraries familiar to you; on Windows, they are often very close in functionality. I don't expect they would be much trouble to your. Tempfile is a little bit more confusing (it is loaded down with security "features," which are mostly irrelevant in our work), and argparse and subprocess do require study. This is, to some extent, the old decision as to use libraries or roll your own code. The standard advice is to use libraries for the sake of maintenance, since they are already debugged and documented, but libraries can sometimes load you down with complexities unnecessary to your work. Overuse of libraries can weigh your programs down; one can, for instance, end up with XML formats when simple text files will do. I am forming some thoughts on the broader issues, but I will wait for them to gel before posting them, I think. Randolph
