python - 如何使用 while 循环从用户输入中附加任意数量的键和多个值的字典

Question

print('Scenario Analysis')

profit_dict = {}

while True:
    item1= input ('What is the item: ')   
    price_good= int (input('What is the expected profit of {}, in the best case scenario: '.format(item1)))
    price_bad = int( input ('What is the expected profit of {}, in the worst case scenario: '.format(item1)))
    user_choice= input('Do you have anymore items: ')
    if user_choice in ['Yes','yes','y','Y']:
            pass
    else:
            break

profit_dict[item1]=price_good,price_bad

#EVERYTHING FROM HERE ON IS NOT RELEVANT DIRECTLY TO QUESTION BUT PROVIDES CONTEXT

print('This is your best profit outcome: ')
for values in good_dict.values():
    total_list=(max(values))
    print(total_list)

print('This is your worst profit outcome: ')

我知道变量的使用将不断取代字典，但这是我可以展示我的目标的最佳方式。可能使用函数而不是 while 循环可能会有所帮助，但我不确定。

提前感谢您的任何回复。

profit_dict = {}

while True:
    item1= input ('What is the item: ')   
    price_good= int (input('What is the expected profit of {}, in the best case scenario: '.format(item1)))
    price_bad = int( input ('What is the expected profit of {}, in the worst case scenario: '.format(item1)))
    user_choice= input('Do you have anymore items: ')
    profit_dict[item1]=[price_good,price_bad]    
    if user_choice in ['Yes','yes','y','Y']:
            continue
    else:
            break

print(profit_dict)

这是你想要的 ？这只是继续添加字典，直到用户输入是。
