From: Gunnar Horrigmo <horrigmo <at> runbox.no> To: bug-gnu-emacs <at> gnu.org Subject: 28.0.50; Python shell doesn't echo if shebang Date: Wed, 16 Sep 2020 15:23:22 +0200
Open a .py file M-x run-python RET In .py file, write some statement, say "1+2" and evaluate it with (f.ex.) python-shell-send-statement. Observe that python shell echoes the result, "3", and prompts on a new line. Add a shebang to the top of .py file (f.ex. "#!/usr/bin/pyton3" on my system). Evaluate the same statement as over. Observe that python shell doesn't echo the result, but does print a new prompt, but without a newline. You can add and remove the shebang as much you want, and see the echo behaviour change accordingly. You do _not_ need to save the file. You can see a replay of the issue here: https://asciinema.org/a/DOq15ldlyiKI5HKLrKpF7gIeg I've verified this behaviour using emacs -Q on versions 28.0.50 (including master HEAD as of 2020-09-16) and 27.1.50. And it seems all the python-shell-send-* functions exhibit the same, not just python-shell-send-statement.
