泡菜。酸洗错误：无法腌制<函数函数在0x02B3C1B0>：找不到__main__.func

Question

test.py 并且 main.py 位于同一文件夹中，并且我执行 main.py，解释器报告以下错误。

蟒蛇环境：蟒蛇2.7.15

如何解决这个问题？

谷歌告诉我这个问题在python3.4中得到了修复，但是我想在python 2.7中使用这种风格，该怎么做 test.py

from multiprocessing import Process, Queue
def interaction(q):
print '*'*50
q.put('-'*50)
q = Queue()
p = Process(target=interaction, args=(q,))
p.start()
p.join()
print q.get()

main.py

if __name__ == '__main__':
execfile('test.py')

错误：

我的预感是execfile()的使用导致了这种情况，因为它使 Python 对__main__是什么感到困惑。

您可以改为导入test模块(顺便说一句，应该将其重命名为更具描述性的名称(。
