Tips for Starting a New Life
You should also know that not all widgets provide a command option. Most of the various Button widgets (RadioButton, CheckButton, etc.) do. And others provide similar options (e.g. scrollcommand). But you really have to investigate each different kind of widget to find out whether it supports command binding. But by all means learn about the command option for the widgets that you will be using. It will improve the behavior of your GUI, and make your life as a coder easier.
Modal dialogs are used for quick interactions with the user or for any time that information in a dialog absolutely must be entered before the user can move forward in the program. Within wxPython, there are several standard functions to display basic modal dialogs. These dialogs include alert boxes, one line of text entry, and choosing from a list. In the following sections, we'll show you what these dialogs look like, and how using the predefined functions will make your life easier.
This is a fairly nifty trick, because it makes it difficult for test-breaking bugs to get into the repository unnoticed. Somewhat like code coverage, though there's potential for trouble if it becomes a matter of policy rather than simply being a tool to make your life easier.
That about covers unary operators, which brings us up to the second type of operator in Python, binary operators. In this case, binary doesn't mean the mathematical base that consists of only zeroes and ones, it means the idea of operators that have two arguments. This sounds strange, but I assure you, you have been using them most of your life without even thinking of them as binary. For example, x + y uses the binary operator +. It applies to two variables, x and y.
If you have gotten this far, we should point out that you, the reader, have an advantage many people do not. If you decided to pick up a book on Python for Unix and Linux system administration, then you most likely know something about how to execute commands from a shell. This is a tremendous advantage to learning to become a Python programmer. Having an understanding of the way to execute commands from a terminal is all that is required for this introduction to Python. If you truly believe you will learn how to program with Python, then read the next section immediately. If you don't believe it yet, then reread this section again, and convince yourself it really is just a matter of getting your mind to understand you do have the power to learn how to program in Python. It is really that simple if you make this decision, it will change your life.
When informed people consider the duties of a system administrator, building GUI applications probably does not come to mind at all. However, there are times when you will need to build a GUI application, or by building a GUI app your life will be easier than if you didn't. We're using GUI in the broad sense here to mean both traditional GUI applications using toolkits such as GTK and QT, as well as web-based applications.
