[Python3][Resolved] TypeError: descriptor '__init__' requires a 'super' object but received a 'str'

Source code

class Contact:
    def __init__(self, first_name, last_name):
        self.first_name = first_name
        self.last_name  = last_name
        self.full_info  = first_name + " " + last_name
    def print_contact(self):
        print(self.full_info)
       
class EmailContact(Contact):
    def __init__(self, first_name, last_name, email):
        super.__init__(first_name, last_name)
        self.email = email
        self.full_info = email

email_contact = EmailContact("test","person","test@person.com")

Problem and correct 

In this case, this problem is related to mistype of calling super class, it should be super().super.__init__(first_name, last_name) but not super.__init__(first_name, last_name) :

class Contact:
    def __init__(self, first_name, last_name):
        self.first_name = first_name # use self to create property
        self.last_name  = last_name
        self.full_info  = first_name + " " + last_name
    def print_contact(self):
        print(self.full_info)
       
class EmailContact(Contact):
    def __init__(self, first_name, last_name, email):
        super().__init__(first_name, last_name)
        self.email = email
        self.full_info = email
