Saving attributes to an object in Python

Question

I'm practicing OOP concepts in Python, and I came across this problem:

class User:
    def __init__(self, username, email, password, 
        firstname, lastname, phone):

        self.username = ""
        self.email = ""
        self.password = ""
        self.firstname = ""
        self.lastname = ""
        self.phone = ""

user=User('x','y','z','f','v','c')
print(vars(user))

Result:

{'username': '', 'firstname': '', 'lastname': '', 'phone': '', 'password': '', 'email': ''}

The values are not saved to the object. How can I fix this?

Answer 1

You need to assign the function arguments to the instance variables.

class User:
    def __init__(self, username, email, password, 
        firstname, lastname, phone):

        self.username = username
        self.email = email
        self.password = password
        self.firstname = firstname
        self.lastname = lastname
        self.phone = phone

user=User('x','y','z','f','v','c')
print(vars(user))

Answer 2

Save the constructor arguments to the appropriate instance variables:

def __init__(self, username, email, password, firstname, lastname, phone):
    self.username = username
    # etc.
