Python subprocess in Windows

Question

I try to use "ren" command with Python 3.6.3 subprocess in Windows

Code:

import subprocess, os

path = r"C:\Users\user\Desktop\Temp"

subprocess.check_output(["ren", os.path.join(path, "ABC.txt"), os.path.join(path, "Hello.txt")], shell=True)

but I get Error: "subprocess.CalledProcessError"

Please help!!

thanks

What error number does CalledProcessError indicate?

According to the ren command manual you can set only filename that you need to change current file not drive and folder:

try fixed code

import subprocess, os

path = r"C:\Users\user\Desktop\Temp"

subprocess.check_output(["ren", os.path.join(path, "ABC.txt"), "Hello.txt"], shell=True)
