New submission from Joel Croteau <jcrot...@gmail.com>:
It would be nice if, after a threading.Thread has completed its run, it were possible to retrieve the return value of the target function. You can do this currently by setting a variable from your target or by subclassing Thread, but this should really be built in. My suggested changes: * Add an attribute to Thread, retval, initially set to None, that contains the return value of the target after a successful completion. * Thread.run() should set self.retval to the return value of the target upon completion, and also return this value. * Thread.join() should return self.retval after a successful completion. If you're not using Thread.join(), you can directly access Thread.retval to get the return result after a successful run. Thread.run() and Thread.join() both return None in all cases now, so I think a change in their return value would have minimal if any effect on existing code. ---------- components: Library (Lib) messages: 340815 nosy: Joel Croteau2 priority: normal severity: normal status: open title: Allow retrieval of return value from the target of a threading.Thread type: enhancement versions: Python 3.8 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue36717> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
