use str as variable name

[Mathieu Prevot]

Hi,

I have a program that take a word as argument, and I would like to
link this word to a class variable.

eg.
class foo():
width = 10
height = 20

a=foo()
arg='height'
a.__argname__= new_value

rather than :

if arg == 'height':
a.height = new_value
elif arg == 'width';
a.width = new_value

Can I do this with python ? How ?

Thanks,
Mathieu

Not quite sure what the above is supposed to achieve

rather than :

if arg == 'height':
a.height = new_value
elif arg == 'width';
a.width = new_value

setattr(a, arg, new_value)
