from multiprocessing import Pool p = Pool(5) def f(x): ... return x*x ... p.map(f, [1,2,3])

This example in the document is confusing because this is already wrong code when run with fork method even if you run it as a script. With fork start method, f should be defined before p is created. Also, just advising that one shouldn't use interactive shell and should run multiprocessing code in if __name__ == '__main__' is not informative becuase those conditions are generally no problem with fork method. Can I try improving the documentation? ---------- assignee: docs@python components: Documentation messages: 316892 nosy: Derek Kim, docs@python priority: normal severity: normal status: open title: possible documentation improvement proposal for multiprocessing versions: Python 3.8 _______________________________________ Python tracker <report@bugs.python.org> <https://bugs.python.org/issue33553> _______________________________________
