I understand this book. The other book we are using, I setup the code in text editor Geany. This code phrases import, stdio, import, stdio, write, writeln are not executed in Geany. Am I supposed to be using a different text editor?

Elements of Programming .1 Your First Program IN THIS SECTION, OUR PLAN taking you through the basic steps required to get a simple program running. The Python system (hereafter abbreviated Python) is a collection of applications, not unlike many of the other applications that you are accustomed to using (such 1.1.1 Hello, World s your word processor, e and web browser). As with any applica tion, you need to be sure that Python is properly installed on your computer. It comes preloaded on many computers, or you can download it easily. You also n a text editor and a terminal application. Your first task is to find the instructions for installing such a Python programming environment on your computer by visiting is to lead you into the world of Python programming by 4 Using a command-line argument Programs in this section . .7 mail program, 1.1.2 eed http://introcs.cs.princeton. edu/python We refer to this site as the booksite. It contains an extensive amount of supplemen- tary information about the material in this book for your reference and use while programming. Programming in Python To introduce you to developing Python programs, we break the process down into two steps. To program in Python, you need to: . Compose a program by typing it into a file named, say, myprog ram. py Run (or execute) it by typing python myprogram.py in the terminal window. In the first step, you start with a blank screen and end with a sequence of typed characters on the screen, just as when you write an email message or an essay. Pro grammers use the term code to refer to program text and the term coding to refer to the act of creating and editing the code. In the second step, you transfer control of the computer from the system to your program (which returns control back to the system when finished). Many systems support several different ways to compose and execute programs. We choose the sequence given here because it is the simplest to describe and use for small programs Composing a program. A Python program is nothing more than a sequence of characters, like a paragraph or a poem, stored in a file whose name has a .py exten sion. To compose one, therefore, you need simply define that sequence of charac
