 Python does have a slightly odd (compared to other languages)
 interpretation of variable assignments (name bindings, really)
 inside a class block. Trips up a lot of people.

Changed the code: 10% smaller, more elegant, and it seems to work!
If it really works I am close to half-way...

stupid simple scope issue

[JohnD]

After 5 year of no Python programming I decided that I needed to brush
up my skills. Started writing on a reasonably complicated problem.
Unfortunately my basic Python skill are gone.

I present the bare-bore problem. This code does not produce the expected
result: can anyone tell me why? As you will guess, I want the first
three lines of output identical to the second three lines...

Can anyone point out the solution? Thanks!

#~/usr/bin/python
import random
class boys:
state={}
class boy:
state={
'name':'',
'age':''
}
names=['a','b','c']

def add_names():
global boys
for n in names:
boy.state['name']=n
boy.state['age']=random.randint(1, 1000)
boys.state[n]=boy.state
print boy.state['name'], boy.state['age']

add_names()

for n in boys.state:
boy.state=boys.state[n]
print boy.state['name'], boy.state['age']

Thank you very much. The dust is slowly starting to move.
The code posted is nothing like the real thing, but I tried
to capture the essence. 

From your commants I think I see my mistake.

Thank you very much for your reply!
