Perhaps the OP means that 'name' is a variable which is bound to the
name of the function/method, which is an attribute of self.blahbalah.

If 'name' is bound to the name, then:

     func = getattr(self.blahblah, name)
     func(arg1, arg2, arg3)

or just:

     getattr(self.blahblah, name)(arg1, arg2, arg3)
