Creating a GUI using Python, WxWidgets, and wxPython After putting off this tutorial for as long as I possibly could (I’m not sure why) I have finally decided to buckle down and learn how to use WxWidgets using the WxPython Python bindings. Installing Getting WxWidgets and WxPython installed on my Debian Linux computer was as simple as installing the python-wxgtk2.6 Debian package. If you have any problems installing wxPython on your computer I suggest that you follow the instructions in the wxPython FAQ. Or you can follow the Getting Started instructions on the wxPython wiki. Setting up the Window Now that you have WxWidgets and WxPython installed it’s time to write a quick wxPython application. import wx if __name__ == "__main__": app = wx.App() app.MainLoop() Save the file as wxHello.py, or whatever you would like. The next thing that we do is create a wx.App and then call it’s MainLoop function, which starts the main GUI event loop. Notice the last little instruction there: It’s not much but it’s a start.

Introductory Computing, using Python as the high level language 5. binary numbers, the bit (b), byte (B) and word Computers have millions of pieces of hardware (memory/registers) that are in one of two states up/down (N/S) (magnetism, harddisk) switch on/off voltage high/low current high/low These states are represented by 0/1 You don't have to know what the hardware is doing or even what the hardware technology is, or whether a 0 is represented by high or low voltage. Some hardware maintains its state without power e.g. floppy disks harddisks flash memory Most hardware looses its state when switched off e.g. RAM (random access memory in the computer) how much memory is in a typical hard disk, flash disk, floppy disk, RAM [1] ? Since there are only two states (two = bi), the state is represented by a binary digit (called a bit). 5.1. The number system in common daily use is called decimal. 5.2. bit, wikipedia ( The value represented by each digit in the number 102 depends on it's position. From this we find 5.5. 6. 6.2.
