OO

[Egbert Bouwman]

Hi Paul,
Your explanation of OO in the context of Python was very usefull,
especially as Python is the only OO language that I more or less do
understand. I would like to read much more of this tutorial kind 
of stuff, because reinventing the wheel is just beyond my capabilities.

For some time already I thought I had a problem: will I write my database
output to normal stdout, or to a GUI window. You gave this question a new
dimension, because it is not or/or anymore:

> Now I can say 
> 
> sys.stdout=myOutputClass1() 
> 
> and hundreds of pieces of code that were supposed to work on the stdout
> "stream" will magically work on myOutputClass. When they say:
> sys.stdout.write( "foo" ), it calls the appropriate write method.
> 
> The fact that it has the right methods is enough to make it "stand in"
> for a stream. 

My problem seems to boil down to an extra method. Thanks.
