Question

I am learning OOP with python.
I want to implement something like to display:
firstName, lastName of a person with address as dictionary like, 'state': someState, 'city': someCity

I’ve done:

class data:
    def __init__(self, firstName, lastName, **address):
        self.firstName = firstName
        self.lastName = lastName
        self.address = {
            "state": self.state,
            "city" : self.city
        }

When I did:

>>> d = data("a", "b", 'state' : "stat", 'city' : "ci")
SyntaxError: invalid syntax
>>> d = data("a", "b", 'state'="stat", 'city'="ci")
SyntaxError: keyword can't be an expression

Is there mistake with my code or the syntax of accessing dictionary is mistake. I can not figure it out.

Answer 1

You should just define a new dict as the argument to your constructor and then copy it in the constructor like this.

class Data:
    def __init__(self, firstName, lastName, address):
        self.firstName = firstName
        self.lastName = lastName
        self.address = dict(address)

data = Data("first", "last", dict(state="pa", city="pittsburgh"))
