[Tutor] dictionary dispatch for object instance attributes question

[Liam Clarke]

Hi, 

just an expansion on Brian's query, is there a variant of getattr for
instance methods?

i.e. class DBRequest:
    def __init__(self, fields, action):
        self.get(fields)
    
    def get(self, fields):
        print fields


Instead of self.get in _init__, the value of action to call a
function? Or, is it going to have to be dictionary dispatch?

Regards, 

Liam Clarke
