Eryk Sun added the comment:
`cmd.exe dir` ignores the unrecognized `dir` argument and runs the interactive
shell. The shell is waiting for input on stdin. You can type "exit" and press
enter to return to Python.
When you run this from IDLE (i.e. via pythonw.exe), there's no StandardInput
New submission from sanjay patel :
Below snipped goes to infinite loop when running through windows command prompt
but works in python IDLE
import subprocess
subprocess.check_output('cmd.exe dir', stderr=subprocess.STDOUT)
save as:test.py
in windows cmd use command: python test.py
then it goe
