Question

我已经达到了可以计算总膳食成本的点，给出了一系列倾翻百分比：

def total_cost(price,tax,tip):

    bill = price+(price*tax)+((price+(price*tax))*tip)
    return bill

for tip in range(15,30,5): 

    cost = total_cost(20, 0.1350, tip/100.)  
    print(cost)

在混合以下问题中的多个变量时我感到难过：

您将在下面找到一本字典，其中包含不同州的税率，以百分位数表示。遍历所有州并打印餐食价值，税前食品价格为20美元;显示尖端百分比的价格为15％，20％和25％。“

tax = {
    "Alabama": 13.50,

    "Alaska": 7,

    "Arizona": 10.73,

我认为如果你自己解决这个问题会更好，你会从中学到更多。

我可以给你的提示是这个代码迭代你给出的字典中的每个键，并在该状态下打印税。

for name_of_key in tax:
  print("Tax in state %s: %f" % (name_of_key, tax[name_of_key]))
