Yes, that is that cause of the observed behavior. See the first note in the remarks section on the relevant MSDN entry at http://msdn.microsoft.com/en-us/library/431x4c1w.aspx : """ Spaces embedded in strings may cause unexpected behavior; for example, passing _exec the string "hi there" will result in the new process getting two arguments, "hi" and "there". If the intent was to have the new process open a file named "hi there", the process would fail. You can avoid this by quoting the string: "\"hi there\"". """ The 'exec' functions are more low level and more arcane than most people would like. Python exposes that functionality with all its beauty and all its warts. David Murray is right in saying that you likely need one of the higher level modules such as subprocess with shell=True. I looked through the code in Modules/posixmodule.c and didn't any code on our part that exacerbates the behavior. I recommend closing this as just one of the facts-of-life when dealing with low level functionality. ---------- nosy: +rhettinger _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue20451> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
