使用 Python IDLE 无法看进程通信的输出。

搜索后，得到的答案是：

Well, IDLE is a strange thing. In order to "capture" everything what you write using print statements orsys.stdout.write, IDLE "overrides" sys.stdout and replaces it with an object that passes everything back to IDLE so it can print it. I guess when you are starting a new process from multiprocessing, this hackery is not inherited by the child process, therefore you don't see anything in IDLE. But I'm just guessing here, I don't have a Windows machine at the moment to check it. – Tamás May 6 '10 at 9:10
