>>> 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? |
