Running an outside program (executable) in Python?

I just started working on Python and have been trying to run an outside executable from Python. I have an executable for a program written in Fortran. Let’s say the name for the executable is flow.exe, and my executable is located in C:\Documents and Settings\flow_model. I tried both os.system and popen commands, but so far, I couldn't make it work. The following code seems like it opens the command window, but it wouldn't execute the model. # Import system modules import sys, string, os, arcgisscripting os.system("C:/Documents and Settings/flow_model/flow.exe") How can I fix this?
Those whitespaces can really be a bother. Try os.chdir('C:/Documents\ and\ Settings/') followed by relative paths for os.system, subprocess methods, or whatever... If best-effort attempts to bypass the whitespaces-in-path hurdle keep failing, then my next best suggestion is to avoid having blanks in your crucial paths. Couldn't you make a blanks-less directory, copy the crucial .exe file there, and try that? Are those havoc-wrecking space absolutely essential to your well-being...?
