Amaury Forgeot d'Arc added the comment: "solution.put(c)" takes a *reference* to the list c. And then the test() function continues running!
By the time the list is serialized and sent back to the main process (in another thread), the test() function has already changed it... As you noticed, you can use immutable objects instead (string, int), or make a copy of the list: solution.put(c.copy()) ---------- nosy: +amaury.forgeotdarc resolution: -> not a bug stage: -> resolved status: open -> closed _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue22600> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
