Martin Panter added the comment: What happens instead of aborting the line at step 3? Is Ctrl+C completely ignored, as if you didn’t press it?
Perhaps matplotlib is interfering with Python’s SIGINT handler and/or PyOS_InputHook(). Can you eliminate ipython from the equation? I.e. does the problem happen with the built-in Python interactive interpreter? Or with a simple script like the following: import readline import matplotlib # Or whatever is needed to trigger it while True: input("PROMPT ") ---------- nosy: +martin.panter _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue26894> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
