When I run IDLE (python 3.8) :

>>> import os
>>> os.system("ls")
0
>>> os.system('echo "test"')
0
>>> os.system("users")
0
>>> 

But if i do :

os.system("ls > test.txt") 

The test.txt file is created and contain the result.

I tried to reinstall and everything, nothing works... Only if I Run python in my terminal, command works but IDLE seems better for work.

Who could help me ? Thank you

I get the same issue and this is what I did:

• Restart the IDLE.
• Restart my laptop.

However, the same problem persists.

My suggestion is, instead of using IDLE, why don't you use the terminal? In my case, I use iTerm.

$ python3.8
$ >>> import os
$ >>> os.system("ls")

And everything works fine.
