Python - Windows 上的子进程输出

Question

我正在尝试使用Python中的“子进程”模块来获取shell的输出，命令是“netsh wlan show faces”。我尝试使用“utf-8”进行解码，“结果”变量是一个字符串，但无论如何它都不起作用。

提前感谢您的帮助！

import subprocess

class LocalNetwork:
    def networkinformations():
        result = subprocess.check_output('netsh wlan show interfaces',shell=True,encoding='utf-8').strip().splitlines()
        print(result)

LocalNetwork.networkinformations()

回溯：

Traceback (most recent call last):
  File "d:\Python\Bibliotheken\NetyPy.py", line 8, in <module>
    LocalNetwork.networkinformations()
  File "d:\Python\Bibliotheken\NetyPy.py", line 5, in networkinformations
    result = sub.check_output('netsh wlan show interfaces', shell=True, encoding='utf-8').strip().splitlines()

这适用于任何拥有以下条件的人： 结果= subprocess.run（命令，capture_output = True，text = True，check = True，encoding =“cp437”）
