Understanding Python super() with __init__() methods [duplicate] 7 answers

---

You need to make a super call to instantiate the object using the parents __init__ method first:

class Person(list):
    def __init__(self, a_name, a_dob=None, a_books=[]):
        #person initialization code
        super(Person, self).__init__(a_books)
        self.name = a_name
        self.dob = a_dob

print Person('bob',a_books=['how to bob'])

Gives the output:

['how to bob']

Because list has a __str__ method.
