If I called subprocess.call with a list argument, it returned code 0 (success) but the generated sphinx code was not the same as when I ran the program from the terminal. I concluded that this is some weird interaction between Idle (which may also run in a subprocess??) and my own program. I also had no problems when I ran (in the terminal): python -c "import subprocess; subprocess.call(['sphinx-apidoc'...(etc)])" I was surprised that the list elements of the argument for subprocess.call *have to be* separate tokens, e.g. (earlier in one of Danny's replies): a token (list element) '-f -F' won't work, it has to be two separate elements/tokens: '-f', '-F'. Apparently, subprocess.call is more than just a convenience function that " ".joins the list and escapes the resulting string. regards, Albert-Jan _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
