Ronald Oussoren added the comment: I don't agree that adding a table/picture is the only thing that can be done, or even that it is a good idea. IMHO the subprocess documentation is clear enough about the distinction between bytes and string, especially in the section about convenience functions that is right at the top of the page. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17860 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue17860] subprocess docs lack info how to use output result
Ronald Oussoren added the comment: The attached patch explicitly mentions that stdin/stdout/stderr are opened as binary streams when universal_newlines is False. I'm not convinced that adding this text will solve the confusion, subprocess has fairly complex documentation due to the rich API and it is easy to mis information when you don't read carefully. That said, the documentation for check_output (which is likely the most common way to run a command and fetch its output) is already clear about the types of the returned data, both in prose and example code. -- nosy: +ronaldoussoren Added file: http://bugs.python.org/file30562/issue17860.txt ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17860 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

New submission from anatoly techtonik: http://docs.python.org/3/library/subprocess.html A common confusion is that result from subprocess calls in Python 3 is bytes, not string, and needs to be converted. The problem is complicated because you need to know the encoding of input/output streams. This should be documented at least. http://stackoverflow.com/questions/606191/convert-byte-array-to-python-string -- assignee: docs@python components: Documentation messages: 187982 nosy: docs@python, techtonik priority: normal severity: normal status: open title: subprocess docs lack info how to use output result versions: Python 3.3 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17860 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

R. David Murray added the comment: Anatoly, do you have a specific suggestion for improved wording? This *is* documented in the subprocess documentation, in several appropriate places, including the fact that the appropriate encoding to use may need to be determined at the application level. -- nosy: +r.david.murray ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17860 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
