Hello Python

Hello Python, this is derived from "Ruby in 20 Minutes"1

Enter the python interpreter.
---------------------------------
Define a function that says 'hello world'.
>>> def h():
...     print "hello world"
...
>>> h()
hello world
Define a slightly more complex function that says hello to the passed name.
>>> def h(name):
...     print "Hello %s!" % name
...
>>> h('Guido')
Hello Guido!
Define a function that says hello to the world, or to the passed name.
>>> def h(name = 'World'):
...         print "Hello %s!" % name
...
>>> h()
Hello World!
>>> h('Guido')
Hello Guido!
If we want our object to remember our name, we would use a class. Enter the 'Greeter' class.
>>> class Greeter:
...         def __init__(self, name = "World"):
...                 self.name = name
...         def say_hi(self):
...                 print "Hello %s!" % self.name
...         def say_bye(self):
...                 print "Goodbye %s. Please come again." % self.name
...
>>> g = Greeter('Guido')
>>> g.say_hi()
Hello Guido!
>>> g.say_bye()
Goodbye Guido. Please come again.
>>> g.name
'Guido'
>>>g.name = 'Syn'
>>> g.say_hi()
Hello Syn!
Now for fun lets write a 'MegaGreeter' that can handle multiple names.
>>> class MegaGreeter:
...         def __init__(self, name = "World"):
...                 self.name = name
...         def say_hi(self):
...                 if isinstance(self.name, list) or isinstance(self.name, tuple):
...                         for i in self.name:
...                                 print "Hello %s!" % i
...                 else:
...                         print "Hello %s!" % self.name
...         def say_bye(self):
...                 if isinstance(self.name, list) or isinstance(self.name, tuple):
...                         print "Goodbye %s. Please come again!" % ", ".join(self.name)
...                 else:
...                         print "Goodbye %s. Please come again!" % self.name
...
>>> mg = MegaGreeter(['Guido', 'Syn', 'Ninja'])
>>> mg.say_hi()
Hello Guido!
Hello Syn!
Hello Ninja!
>>> mg.say_bye()
Goodbye Guido, Syn, Ninja. Please come again!
>>> mg = MegaGreeter()
>>> mg.say_hi()
Hello World!
>>> mg.say_bye()
Goodbye World. Please come again!
>>> dir(MegaGreeter)
['__doc__', '__init__', '__module__', 'say_bye', 'say_hi']

9 ways to count to 10

I may actually be getting this programming thing down. It started life as a perl script, moved to python, and now its redone in glorious C.

fedora 7 and sucky ATI drivers

******* Resolution issues/ATI driver issues **************

ati-fglrx driver has issues with xorg reporting version 1.6
Can't we all just get along?

1) downgrade xorg here
$ rpm -U --oldversion xorg-x11-server-Xorg-1.2.0-6.fc7.i386.rpm
2) tell yum not to upgrade xorg
$ exclude=xorg-x11-server-Xorg*
3) create xorg.conf
$ aticonfig --initial
4) update /etc/X11/xorg.conf
