Defining an object's argument whose name is stored in a variable

[arbiel]

Hi everybody

Window being a class, I define an Window objet's argument whose name is stored in a variable with the following code :

w=Window()
arg='toto'
val='any value'
exec('w.'+arg+'=val')
w.toto
'any value'

Generally speacking, using «exec» is not a very good practice.

Is there a smarter way to proceed ?
