I have downloaded python on my computer. But I am still not clear on how to write a program and save with a file name from the command prompt, and then run it from the command prompt. Where do I write the script and save the file as a py file ?

Hi mahesh gurbaxani,

after you have installed python on your windows machine, open the command line and type in python if you receive an error message or if you see the python 2.x version then try to type in python3. If you still receive an error message, then you have to add the python 3 directory to your PATH variable.

You do that by right clicking on Computer and select properties. In the left column select Advanced System Settings. In the System properties window click on the Advanced tab and chose environment variables. Search for the PATH variable. There you should see something like c:\blabla\bin;c:\some_more;.

Go to the end and add a semicolon if there isn't already one. Now add the path of your Python 3 directory, thus where you have installed it, which should look something like this c:\Python34.

Restart your computer, open the command line tool and type python3. You now should get the python3 prompt. Let me know if that helped.
