如何使用python在多个终端窗口中运行多个文件 [英] How do you run multiple files in multiple terminal windows using python

问题描述

from subprocess import call
call(["python3", "/home/johngr/psdirc/TestBot1.py"]) and call(["python3", "/home/johngr/psdirc/TestBot2.py"]) and call(["python3", "/home/johngr/psdirc/TestBot3.py"])

调用正在运行，但它只运行第一个文件.我希望它们都在自己的终端窗口中运行.

The call is working but it only runs the first file. I want them all to run in their own terminal windows.

推荐答案

不要使用和，一个接一个地运行:

Don't use and just run one after the other:

call(["python3", "/home/johngr/psdirc/TestBot1.py"])
call(["python3", "/home/johngr/psdirc/TestBot2.py"])
call(["python3", "/home/johngr/psdirc/TestBot3.py"])

如果您不希望他们在开始下一次使用 Popen 之前等待进程完成:

If you don't want them to wait for the process to finish before starting the next use Popen:

 Popen(["python3", "/home/johngr/psdirc/TestBot1.py"])
 Popen(["python3", "/home/johngr/psdirc/TestBot2.py"])
 Popen(["python3", "/home/johngr/psdirc/TestBot3.py"])

call 将运行由 args 描述的命令.等待命令完成，然后返回 returncode 属性. 其中 Popen 不会等待.

call will Run the command described by args. Wait for command to complete, then return the returncode attribute. where Popen won't wait.

如果您想确保每个进程以非零退出状态退出，请使用 check_call 它将为任何非零退出状态引发 CalledProcessError.

If you want to be sure each process exits with a non-zero exit status use check_call which will raise a CalledProcessError for any non-zero exit status.

要为每个终端打开一个终端，您可以使用 gnome-terminal 和 -e 在终端内执行此选项的参数:

To open a terminal for each you can use gnome-terminal with -e Execute the argument to this option inside the terminal:

call(['gnome-terminal', '-e', "python3 /home/johngr/psdirc/TestBot1.py"])
call(['gnome-terminal', '-e', "python3 /home/johngr/psdirc/TestBot2.py"])
call(['gnome-terminal', '-e', "python3 /home/johngr/psdirc/TestBot3.py"])

如果你想打开标签，你可以使用 --tab -e:

If you want to open tabs you can use --tab -e:

cmd =['gnome-terminal', '--tab', '-e', 'python3 /home/johngr/psdirc/TestBot1.py',
      '--tab', '-e','python3 /home/johngr/psdirc/TestBot2.py','--tab', '-e', 
      'python 3 /home/johngr/psdirc/TestBot3.py']
call(cmd)

您似乎没有 gnome-terminal，因此只需将其替换为 lxterminal:

You don't seem to have gnome-terminal so just replace it with lxterminal:

call(['lxterminal', '-e', 'python3 /home/johngr/psdirc/TestBot1.py'])

不确定是否支持 --tab 选项，我在文档中没有看到任何对它的引用.

Not sure if --tab option is supported or not, I don't see any reference to it in the documentation.
