如何使用此Python显示游戏的成本

我如何使用Python显示游戏的成本，使用如下代码：

if game_list[game]>= 10:
                print ("The Price for this Game is: $"), game_prices[game]*1.1  

---

如果这是python3.x，则必须按照以下步骤执行：

if game_list[game]>= 10:
    print ("The Price for this Game is: $", game_prices[game]*1.1)

对于python2.7，它将是：

if game_list[game]>= 10:
    print "The Price for this Game is: $"+game_prices[game]*1.1

---

您最好授权价格设置逻辑：

def game_price(game):
    price = game_list[game]

    if price >= 10:
        markup = 0.1
    else:
        markup = 0.2

    return price * (1. + markup)

print("The game's price is ${:0.2f}".format(game_price(game)))
