Terry J. Reedy <tjre...@udel.edu> added the comment: The RESTART line means that you ran this in IDLE and that your program crashed the separate (sub)process that was running your code. When IDLE notices this, it starts a new subprocess.
To test whether this is an IDLE-only problem, I ran your code without IDLE. C:\Users\Terry>python -i -m tem >>> doFind() R 6 12 R 12 22 R 21 32 C 10 21 C 13 22 C 16 23 and quickly got the the Windows 'Program has stopped running' box, with no Python error message. Ditto when run on 3.7.0a2. Since this is not an IDLE issue, I revised the title. ---------- nosy: +terry.reedy stage: -> test needed title: Python problem - == RESTART: Shell ===== -> Python crashes with mutually recursive code versions: +Python 3.7 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue32022> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
