> TITLE: python to call or start a fortran a.out Please do consider the title of your posts more carefully. The title you chose here was unfortunate, as it will not provide an intuitive link between the problem and the solution, therefore, it is unlikely that someone with the same _general_ problem, will benefit from this exchange in the future. The _general_ problem here had nothing to with Fortran, much less a specific file or executable named "a.out". So a better title would have been: "How to run an executable from Python", or: "How to spawn a subprocess from Python and capture the result". Or even: "How to poke my OS with a sharp stick, using Python". Perhaps the last example was a bit too generalized, i admit, but you get the point. :-) A good template for composing questions on internet forums is as follows: MESSAGE_TITLE: "A concise, generalization of the problem here..." MESSAGE_BODY: " An elaborate and specific explanation of the problem here..." Mentioning "Fortran" and "a.out" in the body of the message, would be fine. One of the happy-accidents[1] of composing thoughtful queries, is that, many times you will happen upon the answer to your own question during the composition process, and even if you don't, at least you will have a much better chance of receiving prompt and quality responses by following this template. So either way, it's a win-win. [1] Think "Bob Ross" here. As his most important contribution to society was that he taught us all a very important lesson. Namely, that all accidents can be "happy accidents". An eternal optimist, he was... -- https://mail.python.org/mailman/listinfo/python-list
