从打开新命令提示符的 os.Popen 中读取文本

Question

我正在使用 os.Popen 打开一个新的命令提示符窗口并运行一个进程。如何阅读该命令提示符中的文本。请帮助。

import os

def OpenServers():
        os.chdir(coreServerFullPath)
        process=os.popen("start cmd /K CoreServer.exe -c -s").read()
        print(process) #Prints nothing

这是我要打印的命令提示符中显示的输出文本。

编辑：

我也试过这种方法，但是没有运气

 from subprocess import Popen, PIPE, STDOUT
 def OpenServers():
        os.chdir(coreServerFullPath)
        result = subprocess.Popen(['start', 'cmd', '/k', 'CoreServer.exe -c -s'], shell=True, stdin=PIPE, stdout=PIPE, stderr=STDOUT, close_fds=True)
        time.sleep(4)
        output=result.stdout.read()
        print(output) #Prints nothing

新编辑：

我试过这样的事情。问题是，它让我跑了 2 次。我第一次运行时，控制台是空白的。第二次运行时，它运行正常，但出现错误，因为我只能打开一个服务器实例。

def Test1():
        os.chdir(coreServerFullPath)
        result = subprocess.check_output(['CoreServer.exe', '-c', '-s'])
        print(result.stdout)

这是我尝试的完整代码。我只能以管理员身份运行 CoreServer，所以这样做
