Question

我已更新此问题以在多处理脚本中显示我的问题，该脚本不从PythonWin运行（通过按F5），但是从命令提示符运行。我的剧本： -

"""
File Name: simple multiprocess example.py
Description:
A very basic multiprocessing script to show the use of daemon.
There are two processes:-
p1 - calls listen() and runs in the background (daemon = True)
p2 - calls write()
"""
import multiprocessing
import time
import sys

def listen():
    p = multiprocessing.current_process()
    p_name = str(p.name)
    pid = str(p.pid)
    while 1:
        print "%s process with PID %s running: %s" % (p_name, pid, time.asctime())
        time.sleep(1)
    print 'Exiting :', p.name, p.pid

def write():
    p = multiprocessing.current_process()
    p_name = str(p.name)
    pid = str(p.pid)
    for x in xrange(3):
        print "%s process with PID %s running: %s" % (p_name, pid, time.asctime())
        time.sleep(1)
    print 'Exiting :', p.name, p.pid

if __name__ == '__main__':
    p1 = multiprocessing.Process(name='listen', target=listen)
    p1.daemon = True

    p2 = multiprocessing.Process(name='write', target=write)
    p2.daemon = False

    p1.start()

    p2.start()
    time.sleep(7)

当我从PythonWin运行上述脚本时（通过按F5），会出现一条弹出消息（标题为“Python for Win32”），说“无法从-c加载文件” 我的文件名在哪里有完整路径。

当我从命令提示符运行相同的脚本时，它似乎运行完美而没有任何问题。当我从命令提示符运行它时，我得到以下输出： -

s>"simple multiprocess example.py"
listen process with PID 4564 running: Tue Jan 04 09:32:49 2011
write process with PID 3744 running: Tue Jan 04 09:32:49 2011
listen process with PID 4564 running: Tue Jan 04 09:32:50 2011
write process with PID 3744 running: Tue Jan 04 09:32:50 2011
listen process with PID 4564 running: Tue Jan 04 09:32:51 2011
write process with PID 3744 running: Tue Jan 04 09:32:51 2011
listen process with PID 4564 running: Tue Jan 04 09:32:52 2011
Exiting : write 3744
listen process with PID 4564 running: Tue Jan 04 09:32:53 2011
listen process with PID 4564 running: Tue Jan 04 09:32:54 2011
listen process with PID 4564 running: Tue Jan 04 09:32:55 2011

我在网上找不到与此问题有关的任何内容。谢谢你的帮助!!

阿米特 P.S：我在Windows XP，PythonWin，Python 2.6.4v

上运行它

您需要将要运行的代码保存在.py文件中。多处理不支持执行仅在交互模式下输入的代码。

无法在PythonWin中运行任何多处理脚本
