[python] how to run python files in windows command prompt?

I want to run a python file in my command prompt but it does nothing. These are the screen shots of my program i am testing with and the output the command prompt gives me.

You have to install Python and add it to PATH on Windows. After that you can try:

python `C:/pathToFolder/prog.py`

or go to the files directory and execute:

python prog.py

First go to the directory where your python script is present by using-

cd path/to/directory

then simply do:

python file_name.py
