__init__ ? Can some one explane this tome

From the documentation that i've read, Python has no explicit constructors and destructors that you would find in other languages, but __init__ is the closest thing you'll get in Python to a 'constructor'. Basically this 'magic' method (they're called magic methods, the double underscore ones, google 'python magic methods' there are many different ones you can over-load to change the behavior of an object) when defined on a class lets you define how the class is 'constructed' when it is instantiated. So instead of having a class with static attributes, or having to explicitly and separately call a function, you can define certain things in the __init__ method, so when the class is first constructed/an instance is created, all of the things in the __init__ method will happen automatically. The best lesson I saw using a lot of stuff defined in __init__ was the workshop on tkinter. Tkinter lets you build graphical user interface applications with python and Kenneth wrote a large part of that example program in __init__ so that as soon as the script is run, everything in __init__ automatically executes and builds the window with the stuff in it.

Sorry that's a lot and i probably didn't explain it very well but I tried :D

sorry the underscores aren't showing up for some reason, i need to wrap them in backticks i think but you know what i mean.

[Edit: backticks added -cf]
