I am starting Pset 0. How do I write a program in IDLE. As in, I want to be able to write more than one line of code before IDLE runs my code. Thanks!

    You can either use an editor to write your code and IDLE to run it, or grab a program called PyScripter, http://code.google.com/p/pyscripter/, lovely little ide for python that is free.

    from the IDLE shell window you can open an editor window with menu item File | New Window after you have written code in the editor, F5 will run it with the results displayed in the shell window. be sure to save files with a .py extension to preserve the syntax highlighting.

    Just the comments for the assignment are the only thing I can think of until you start importing things.

    When you say that your code didn't work, what "did" it do?

    You are typing in the editor and using F5 to run it?

    You're welcome. Check out PyScripter if you have some free time. I personally prefer that over the IDLE editor.

    IDLE comes with Python, once you download and install the package you will have all you need to write in Python.

    The PyScripter is an IDE for Python, basically the same as the IDLE editor, just with a better user interface.

    The difference between an editor and terminal, is that in the terminal your commands are processed as soon as you hit the enter key.

    so what's the difference between command line and GUI?

    Command line typically refers to a terminal, like if you were to open the "command prompt" in windows. GUI stands for Graphical User Interface, and typically refers to a "windowed" environment.

    but idle is terminal, right? and it's GUI?

    Technically IDLE is a GUI for the terminal.

    so GUI is basically just a better looking terminal, and the editor is where we actually write a program

    Well a GUI is a graphical representation for many interfaces, most likely you are using a GUI web browser to view this page. :)

    An IDE is and Integrated Development Environment. It brings together many of the tasks associated with programming into a nice user interface. You are presented with buttons to build your program, vs having to run a command on the command line.

    hey when does print need parenthesis after it? i saw an example where if the variable is called x, no parentheses are used, and another where the variable is "changing," and parenthese were used...?

    The parenthesis aren't necessary. They most likely give away that the person writing the program was a 'C' programmer.

    so for pset 0 that was it right? three lines? no loops?

    version 3+ of Python requires parens for the print function

    @bwCA beat me to it, I started playing with 3.x last night and discovered that the parenthesis were in fact required. There are some other changes as well that can create a learning speed-bump, so I'd suggest you stick with 2.7.x until you are more familiar with the language.

    And yes, that was it for your ps0, the bulk of the assignment was getting Python installed and familiarizing you with entering code.
