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)

Can I do this with python ? How ?

Thanks,
Mathieu
