Hello,
I am currently on Section 9-17 (Running External Programs) from the Python course. I copied the code exactly as Mosh had, but mine shows an error, and I cannot seem to figure out how to fix it, or what my problem is. Could anyone help? I have attached an image to show my code as well as my error.
Thank you!
I think ls -l is a Mac/Unix thing. It’s used to list all the files in the directory. Windows has some other command.
You can try doing something like subprocess.run(["echo", "test"]) and see if python still works fine?
Hmm, it doesn’t seem to be working. I’m not sure if I am doing something wrong. This is what I get when I run it:
Thanks for the help 
Huh it might be because “echo” isn’t a file.
You can try adding shell=True?
subprocess.run(["echo", "test"], shell=True)
I tried that, and now when I run it in both the output and the terminal, I get: test. This doesn’t seem to be what Mosh gets, however. 
Yes that’s okay, at least we know Python is working fine.
The closest you can get to what he has is if you use
subprocess.run(["dir"], shell=True)
It won’t look exactly the same since he is using a mac. 
I see. Thank you so much for your help! 
I’m using Mac too, but sometimes Mosh’s code don’t work for me too on VSC. Try yourself a PyCharm Community.
Thanks for your help! 
(maybe I should change for mac to learn programming to avoid these weird problem.
