'tuple object is not callable'

Question

import random
from random import *
stack = []
num = eval(input("How many words are there?"))
for x in range(num):
    w = input("What is the word?")
    d = input("Definiton of the word?")
    card = (w , d)
    stack.insert(0, card)
    print(card)
print(stack)
answer = input("What is the word that corresponds with ",    choice(stack[card]))
if answer == w:
    print("Correct!")
else:
    print("Wrong")

'answer = input("对应的单词是什么"，choice(stack[card]))'行不工作，并且返回错误"元组对象不可调用"。我要改变什么?

Answer 1

输入函数最多接受一个参数。你正在经过2。相反，使用字符串格式方法格式化提示，然后将其传递给输入。此外，对choice的调用应该接受可供选择的项目列表，而不是列表中的特定项目，card是一个元组，而不是索引。在你继续之前，你需要回过头来，确保你了解了更多的基础知识。

(word, definition) = choice(stack)
prompt = 'What is the word that corresponds with "{}"'.format(defintion)
answer = input(prompt)
if answer == word:
    print("Correct!")
else:
    print("Wrong")
