Try this: is_alive = multiprocessing.Process.is_alive start = multiprocessing.Process.start id(is_alive) == id(start) If (as I believe it will) this ends up being false, this shows that it's an issue of object lifespan with the values of the expression being temporary method wrappers. From some testing, on my machine on CPython 2.7 this appears to work for any method of any class written in python. While you fixed the typo, it is instructive to note that, as in your original example, multiprocessing.Process.start is multiprocessing.Process.start is *also* False, which would not be the case if the method wrapper were a permanent object. -- https://mail.python.org/mailman/listinfo/python-list
