[issue30079] Explain why it is recommended to pass args as a string rather than as a sequence If shell is True
New submission from Philip Lee: The doc here https://docs.python.org/3/library/subprocess.html#subprocess.Popen says : "If shell is True, it is recommended to pass args as a string rather than as a sequence." but without explain why ? Please add the explanation ! while in https://docs.python.org/3/library/subprocess.html#frequently-used-arguments says: "args is required for all calls and should be a string, or a sequence of program arguments. Providing a sequence of arguments is generally preferred, as it allows the module to take care of any required escaping and quoting of arguments (e.g. to permit spaces in file names). If passing a single string, either shell must be True (see below) or else the string must simply name the program to be executed without specifying any arguments." In the case of shell =True , I found providing a sequence of arguments rather than a string argument can take the advantage of auto escaping and quoting of arguments (e.g. to permit spaces in file names) , so what is the advantage of pass args as a string rather than as a sequence as says in the doc when shell is True? -- assignee: docs@python components: Documentation messages: 291733 nosy: docs@python, iMath priority: normal severity: normal status: open title: Explain why it is recommended to pass args as a string rather than as a sequence If shell is True type: enhancement ___ Python tracker <http://bugs.python.org/issue30079> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue30082] hide command prompt when using subprocess.Popen with shell=False on Windows
New submission from Philip Lee: First, It is nearly useless for the command prompt to pop up during the running time of subprocess.Popen with shell=False. Second, the popping up command prompt would interrupt users and do bad to user experience of GUI applications. Third, I found QProcess within Qt won't pop up the command prompt in using. It would be convenient to add an argument to suppress the command prompt from popping up when using subprocess.Popen with shell=False on Windows, many users are missing the feature and these are many similar feature request questions like the following http://stackoverflow.com/questions/7006238/how-do-i-hide-the-console-when-i-use-os-system-or-subprocess-call http://stackoverflow.com/questions/1765078/how-to-avoid-console-window-with-pyw-file-containing-os-system-call/12964900#12964900 http://stackoverflow.com/questions/1016384/cross-platform-subprocess-with-hidden-window -- components: Library (Lib) messages: 291760 nosy: iMath priority: normal severity: normal status: open title: hide command prompt when using subprocess.Popen with shell=False on Windows type: enhancement ___ Python tracker <http://bugs.python.org/issue30082> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue34221] Any plans to combine collections.OrderedDict with dict
