Re: use str as variable name

En Thu, 04 Sep 2008 04:25:37 -0300, Mathieu Prevot
<ma************@gmail.comescribi�:
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
You're looking for "setattr":

setattr(a, arg, new_value)

http://docs.python.org/lib/built-in-funcs.html#l2h-66
>
Can I do this with python ? How ?

Thanks,
Mathieu
