如何通过 Windows 上的 Python 子进程一次运行多个 shell 命令？

Question

Firstly, please excuse my lack of knowledge; I am a complete beginner at python.

I would like to run several command line commands from within a python script, using the subprocess module. My python script is supposed to be an application that downloads files from a url. These commands are shown below:

set /P _inputname= my-url-here
wget %_inputname%

(wget is in the same directory as my python script)

I have tried using this method:

cmds = ['set /P _inputname=', 'my-url-here', 'wget %_inputname%']
subprocess.run('cmds', shell=True)

However, it fails to run wget .

I understand that my question may seem very similar to this question and this question . However, the solutions in the aforementioned posts have not worked for me. Is there an alternative method?

Answer 1

The posts you mentioned were meant for systems with bash installed (such as most linux distros and other unix like oses)

Though I do not own a windows machine, I presume this will work for you:

(use the & sign to seperate commands)

cmds = ['set', "/P", '_inputname={}'.format('my-url-here'), '&','wget', '%_inputname%']
subprocess.run(cmds, shell=True)

note also that cmds is the variable cmds, not the string
