Question

我们怎样把菜单上所有价格提高10%呢。你知道吗

代码：

burger = {'Fiery Pepper' : 5.65,'McSpicy':'4.85','Quarter Pounder':'4.20','Cheeseburger':'2.35'}
beverages = {'Hot Tea':2.60,'McCafe':2.70,'Coca-Cola':2.65}
menu ={}
menu.update(burger)
menu.update(beverages)
for key in sorted(menu):
    print(key, '->', menu[key] 

Answer 1

将它们乘以原始值的110%：

burgers = {k: float(v) * 1.1 for k, v in burgers.items()}
beverages = {k: float(v) * 1.1 for k, v in beverages.items()}
