AttributeError with python subprocess run

AttributeError: 'list' object has no attribute 'read'
Why am I getting this error and how do I fix this?
This is not specific to ping command but any trivial command for e.g. "dir"

After a lot of hit & trials and hair pulling, I got it working.
It should be instead
subprocess.run('ping localhost', shell=True) #Remove the square brackets
