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 ?

built-in setattr()

Quote:This is the counterpart of getattr(). The arguments are an object, a string and an arbitrary value. The string may name an existing attribute or a new attribute. The function assigns the value to the attribute, provided the object allows it. For example, setattr(x, 'foobar', 123) is equivalent to x.foobar = 123.

setattr(w, 'toto', val)
