Hello All,
I want to build some classes by optimizing their design.
But I want to keep quite 'simples'. I have a XML document
which represents let's say some rules (id, description, value).
My first idea is to create an *docrules* class which holds my document.

Hello Alan,
Oops, then I have a problem.

Andrew,
For starters you have some errors in the way you are trying to access
methods from within a class instances. For example in your code in line 7
and 8,
def main():
angle, vel, h0, time = getInputs()
cball = Projectile(angle, vel, h0)
zenith = 0.0
while cball.getY() >=
There are 2 ways to get the ypos value one is cball.ypos and another is
call.getY() both will give u the current ypos.

Considering that Python is your first programming language, let's start
from the absolute beginning. Before you think about what a function object
is, try to understand what a function is. A function is a series of
python commands put together under a common heading or name in order

Hi all,
If I wanted to have a dictionary containing functions, could I pass
args to those functions? For example:

How would I pass args to f1 or f2 in this case? TIA.
