Set a custom object attribute

Question

I was messing around with inherited classes and wondered if it was possible to set a custom object attribute using a method. It would work something like this:

class MyClass(object):
    def __init__(self):
        super.__init__()
    def setCustAttr(self, name, value):
        #...
g=MyClass()
g.setCustAttr("var",5)
g.var+=6
g.var="text"

• Is there any way to do this?
• Could you use exec("self."+string+"="+value)?

Answer 1

This is what the setattr function does:

setattr(g, 'var', 5)
# g.var is now 5
