multiprocessing.dummy pool：是否可以将多个参数传递给 map 函数？

  • 772

我读到了并行执行。有问题

from multiprocessing.dummy import Pool as ThreadPool

def f(x,y,argv):
     #do something

pool = ThreadPool(4)
pool.map(f, params) #можно сделать так? - [x,y,[argv]]

是否可以将多个参数传递给 map 函数？(x,y,*参数)

总的来说，我阅读了有关线程的信息，因为由于 GIL，线程仍然不能并行执行？流程是否完全自主和并行？

    from multiprocessing.dummy import Pool as ThreadPool

def f(x, y, argv, k=1):
     print(vars())

def decor(func):
    def wrap(arg):
        a, kw = arg
        return func(*a, **kw)
    return wrap

params = (
    ([0, 1, [2, 3]], dict(k=4)),
    ([5, 6, [7]], {}),
)
pool = ThreadPool(4)
pool.map(decor(f), params) #можно сделать так? - [x,y,[argv]]

# out:
# {'argv': [2, 3], 'y': 1, 'k': 4, 'x': 0}
# {'argv': [7], 'y': 6, 'k': 1, 'x': 5}
