python command-line error ('python' is not defined)

Question

I am very new to programming with python. (I am using Windows 10)

So I recently installed Python 3.5.2 and I am trying to write a simple command in the python command line (name of program: Python 3.5):

python -h

What I get:

Traceback (most recent call last):

File "$stdin$", line 1, in NameError: name 'python' is not defined

($ = <> by the way)

When I run it in CMD it works perfectly fine.

Answer 1

You can type in your program and then the command, for example $ ./example.py [-h] . You can also use -? or --help instead of -h

EDIT: In command line,

    $./programName.py [-h] -z

It should show you an error saying that -z is not recognized
