При умножении веса на цену я получаю общую цену как умножение строки, но мне нужно целое число как общая цена

veiws.py:

def sell(request):
    global Price
    Metal = "Metal"
    Steel = "Steel"
    copper = "copper"
    plastic = "plastic"
    Aluminium = "Aluminium"

    if request.method == "POST":
        user = request.user
        Scrap = request.POST.get('Scrap', '')
        Weight = request.POST.get('Weight', '')
        Address1 = request.POST.get('Address1', '')
        Address2 = request.POST.get('Address2', '')
        locality = request.POST.get('locality', '')

        if Scrap.__eq__(Metal):
            Price = 12
        elif Scrap.__eq__(Steel):
            Price = 10
        elif Scrap.__eq__(copper):
            Price = 6
        elif Scrap.__eq__(plastic):
            Price = 2
        elif Scrap.__eq__(Aluminium):
            Price = 30
        x = Price
        price = float(x)

        Total_price = price * Weight

        order = Orders(Scrap=Scrap, Total_Price=Total_price, Weight=Weight, Address1=Address1, Address2=Address2,
                       locality=locality, user=user)
        order.save()

        thank = True
        id = order.order_id
        return render(request, 'Main/sell.html', {'thank': thank, 'id': id})
    return render(request, 'Main/sell.html',)
