It depends on what you mean by long running. A couple of hours seems long to me, others might think in terms of days and weeks. The longest running things I have done are Monte Carlo simulations and a genetic algorithm to find the best integer coefficients for a complex equal ripple filter starting with the floating point coefficients produced by a complex Remez algorithm. I have also used python and mixed numpy/C++ to program an image server to produce photometrically correct, blurred, widefield streaked star images using an indexed Tycho catalog. I mostly use python for quick and dirty programs, prototyping, and as an interface to C++ when speed is essential. Chuck
