我将multiprocessing.Manaager（）。Queue（）的实例对象（q）分配给multiprocessing.Manager（）。dict（）的实例对象（d）的一项，但是我无法重用q在字典中。
Python的版本是2.7.15。
#!/usr/bin/env python

from multiprocessing import Process, Manager
def f(d):
xx = d['10.10.10.102_1024']
xx.put(11)
d['ddd'] = 8888888888
def test1(d,manager):
q = manager.Queue()
try:
d['10.10.10.102_1024'] = q
except Exception as error:
print error
if __name__ == '__main__':
manager = Manager()
d = manager.dict()
test1(d,manager)
p = Process(target=f, args=(d,))
p.start()
p.join()
print(d)
输出
Process Process-2:
