You probably have pyreadline installed. It calls ReadConsoleInputW to read low-level input records, bypassing the console's normal cooked read. See the following file that defines the key binding: https://github.com/pyreadline/pyreadline/blob/1.7/pyreadline/configuration/pyreadlineconfig.ini#L18 Unfortunately pyreadline is broken for non-ASCII input. It ignores the Alt+Numpad record sequences used for non-ASCII characters. Without having to implement readline module for Windows (personally, I don't use it), support for Ctrl+L can be added relatively easily in 3.6+. ReadConsoleW takes a parameter to specify a mask of ASCII control characters that terminate a read. The control character is left in the buffer, so code just has to be written that looks for various control characters to implement features such as a Ctrl+L clear screen. _______________________________________________ Python-ideas mailing list Python-ideas@python.org https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/
