Hello and welcome to the forum, and learning Python!
You should find a tutorial on using the command line on whatever OS you use, namely for commands like cd
(Unix [Linux/OS X]) or dir
(Unix, not sure about Windows though it may be the same). If you're not familiar with file hierarchies yet, as a general computer skill, then you will want to pay attention to those from now on.
Alternatively, there are IDEs that will run your code for you. Since learning to use a command line is arguably harder than basic programming, you may want to do this and then go back to learning the command line later. Tackling both at once could certainly be frustrating. If you're on Windows, then your Python distribution came with an IDE called IDLE* which might show up under your programs as "Python GUI" (I believe). You can get this IDE in OS X as well (and Linux, which I suspect you are not using). IDLE uses two windows, one with your code and one with its output and whatever input you give it, when the main window is the one with your code in it, push F5 on you keyboard and it will run you program in the other window. The one with your input and output also allows you to interactively use Python instead of saving it in a script.
I hope I've provided a fair amount of information here, if you have more questions, feel free to post again and make sure you've read this
so you don't accidentally bother anyone into not helping you. On top of what's there, sometimes screenshots help with people who are very new to programming and use of the command line, but you can use your judgment about whether it's worth it.
* Some people utterly hate IDLE. I'm not one of them, and I think it can be great for people new to the language. I use Sublime Text as my editor, and it runs my code for me when I push F7, but the last time I tried it, it couldn't get user input, and I don't care for the interface. When I use Sublime Text and run my programs, I use the command line.
