You can define new method like get_product- for your Cart class to get your class attribute

For example

class Cart:
    def __init__(self, request):

        self.session = request.session
        cart = self.session.get('cart')
        if not cart :
            cart = self.session['cart'] = {}  #cria a sessão cart
        self.product = cart

    def get_product(self):
        return self.product

And then you can use get_product method after create new object from Cart class:

def cart_view(request):
    cart = Cart(request)
    print(cart.get_product()) # this line where you call your new method 
    if request.user.is_authenticated:
        return render(request, 'cart/cart_page.html')
    else:
        return redirect('account:login')

or you can just override str function:

class Cart:
    def __init__(self, request):

        self.session = request.session
        cart = self.session.get('cart')
        if not cart :
            cart = self.session['cart'] = {}  #cria a sessão cart
        self.product = cart

    def __str__(self):
        return f"{self.product}"

now you can just print out your cart object, it will print your product

def cart_view(request):
    cart = Cart(request)
    print(cart)
    if request.user.is_authenticated:
        return render(request, 'cart/cart_page.html')
    else:
        return redirect('account:login')

you can override the __str__ method on anyclass to control how it is converted to a string... you can also override the __repr__ method if you need to as well

class Cart:
    def __init__(self, request):

        self.session = request.session
        cart = self.session.get('cart')
        if not cart :
            cart = self.session['cart'] = {}  #cria a sessão cart
        self.product = cart

   def __str__(self):
       return f"<CartObject {self.product}>"

...
print(cart)
