我尝试在Pycharm2018.3.3上运行此示例代码，但没有成功。但是相同的代码可以在IDLE上运行而没有任何错误。
我的环境是Python3.7 + Windows10。
from multiprocessing import Process, Queue
def f(q):
q.put([42, None, 'hello'])
if __name__ == '__main__':
q = Queue()
p = Process(target=f, args=(q,))
p.start()
print(q.get()) # prints "[42, None, 'hello']"
p.join()
Process Process-1:
