100 Days of Code 与 Angela Yu 博士的第 9 天秘密拍卖计划

Question

有人可以帮我弄这个吗？我究竟做错了什么？我查看了Angela Yu博士的解决方案。她以不同的方式解决了这个问题，但我无法理解我在哪里犯了错误。

该程序应打印出价最高者的姓名和出价。但是，当我运行此代码时，控制台会打印出价和最后输入的名称。

from replit import clear
#HINT: You can call clear() to clear the output in the console.

from art import logo
print (logo)

game_end = False

bids = {}

while not game_end:

  name = input("What is your name?\n")
  bid = int(input("How much are you bidding? $"))
  
  bids[name] = bid
  game = input("Are there any other bidders. y or n\n").lower()
  
  if game == "n":
    game_end = True
    
  else:
    clear()
    
highest_bid = 0

for bidder in bids:
  if bid > highest_bid:
    highest_bid = bid
    winner = bidder
print(f"The winner is {winner} with a bid of ${highest_bid}")

Answer 1

您没有考虑存储在字典 bids 中的 bid 的值。您只需要在迭代时获取该值：

for bidder, bid in bids.items():
  if bid > highest_bid:
    highest_bid = bid
    winner = bidder
print(f"The winner is {winner} with a bid of ${highest_bid}")

通过使用bids.items()，dict 会生成名称 (bidder) 和出价 (bid)

或者，您可以对 bids 进行排序并提取最后（最高）出价：

winner,highest_bid = sorted(bids.items(), key=lambda item:item[1])[-1]
print(f"The winner is {winner} with a bid of ${highest_bid}")
