.exe中的Python子进程

Question

我正在创建一个python脚本,它将通过网络复制文件和文件夹.它是跨平台的所以我使用cx_freeze创建一个.exe文件

我使用了子进程模块的Popen方法

如果我运行.py文件它正在按预期运行但是当我创建.exe子进程没有在系统中创建

我已经浏览了子进程模块的所有文档,但我没有找到任何解决方案

其他一切(我使用Tkinter也工作正常)正在.exe接受子进程中工作.

任何想法如何在.exe.file中调用子进程？

此文件正在调用另一个.py文件

def start_scheduler_action(self, scheduler_id, scheduler_name, list_index):
       scheduler_detail=db.get_scheduler_detail_using_id(scheduler_id)

这个文件叫做:

    file_obj=open(logFile, 'w')

    if check is False:

        file_obj.write("Problem in connection..Please check connection..!!")
        return

如果你想在exe文件中运行子进程，那么你可以使用

import subprocess

program=('example')
arguments=('/command')
subprocess.call([program, arguments])
