在Windows计算机上从Python运行Linux命令

Question

I am trying to learn how to run command line commands from Python. I am able to do this with DOS:

import subprocess
subprocess.call("dir",shell=True)

This is fine, but I need to be able to do this for linux commands because my company uses linux servers. I am using Mobaxterm to run a local linux session. When I try this:

import subprocess
subprocess.call("ls",shell=True)

I get this error from the terminal:

'ls' is not recognized as an internal or external command, operable program or batch file.

Which sounds ridiculous to me, because ls is clearly a linux command.

If I don't include shell=True I get this error:

Traceback (most recent call last):
  File "ConsolePractice.py", line 4, in <module>
subprocess.call("ls")
File "C:\Users\my_username\AppData\Local\Programs\Python\Python35-32\lib\subprocess.py", line 560, in call
with Popen(*popenargs, **kwargs) as p:
File "C:\Users\my_username\AppData\Local\Programs\Python\Python35-32\lib\subprocess.py", line 950, in __init__
restore_signals, start_new_session)
File "C:\Users\my_username\AppData\Local\Programs\Python\Python35-32\lib\subprocess.py", line 1220, in _execute_child
startupinfo)
FileNotFoundError: [WinError 2] The system cannot find the file specified

So what am I doing wrong? How can I get this to work?

EDIT: Thanks for the comments. Python for Windows won't work for what I'm trying to do. I connected to a linux server and did:

cat > ConsoleCmd.py
import subprocess
subprocess.call("ls",shell=True)
^C
python ConsoleCmd.py

... and ls ran. Found the issue. I'll just have to get my scripts on to the server and run them from there. Thanks everyone

通过在Mobaxterm中打开SFTP会话 ，将python文件传输到服务器，然后直接在服务器上运行该文件（在服务器上已经安装了python），我能够解决此问题。
