Question

我正在做以下字典:

import random

from tkinter.messagebox import YES

name = input("Hello, what is your name? ")
print("nice to meet you {}!".format(name))

instruments = (["Bass","Guitar","Piano"])

instruments1 = ({"Name":"Bass","Price":"US$ 900,00"},
               {"Name":"Piano","Price":"US$ 1000,00"},
               {"Name":"Guitar","Price":"US$ 900,00"})

print("{} we have these instruments for you to buy:".format(name),", ".join(instruments))
#the line above give m all items without the brackets

answer = input("You're going to take some of them? Yes or no.")#waiting the user input

if answer == YES:#boolean command for confirming the yes/no answer. 

    print("{} which one will be?".format(name))
    pos_awnser = input()
    print(pos_awnser,"It's a very good choice.")

elif awnser != YES:
    print("Sorry, we don't have what you need.")  
    print(pos_awnser,"costs",)

我想显示之前选择的工具类型，并在控制台显示名称和价格

Answer 1

不要这样做，而是创建一个字典，就像这样

instruments = ({"Bass":'US$ 900,00',"Guitar":"US$ 1000,00","Piano":"US$ 900,00" })

然后您可以使用打印仪器，

print("{} we have these instruments for you to buy:".format(name),", ".join(instruments.keys())

并通过显示仪器类型

print(pos_awnser, instruments[pos_answer], " is a very good choice.")
