well first of all you have to import the module, but not importing it would give this error
When I try to enter "help(sys)" for example, I just get the error "'more' is not recognized as an internal or external command, operable program or batch file."
based on your error i am guessing you are running windows. However "more" is a feature of linux's Bash. So my first question would be why is your windows python trying to use a bash command? Did you download the windows installer for python, appropriate one for the operating system and archetecture?
