【问题描述】：

import random

quizwords = [["hot", "cold"],["summer","winter"],["hard","soft"],["dry","wet"],["simple","complex"],["light","darkness"],["weak","strong"],["male","female"],["sad","happy"],["win","lose"],["small","big"],["ignore","pay attention"],["sell","buy"],["succeed","fail"],["reject","accept"],["prevent","allow"],["exclude","include"]]

c = 0
random.shuffle(quizwords)
for i in quizwords:
    print(i[0][0],"is to",i[0][1],"as",i[1][0],"is to...")
    ans = input()

到目前为止，这是我的代码，我相信它会输出'e is to c as s is to...' 我试图让它改为说'排除是包含，因为拒绝是......（答案：接受）'

import random

quizwords = [["hot", "cold"],["summer","winter"],["hard","soft"],["dry","wet"],["simple","complex"],["light","darkness"],["weak","strong"],["male","female"],["sad","happy"],["win","lose"],["small","big"],["ignore","pay attention"],["sell","buy"],["succeed","fail"],["reject","accept"],["prevent","allow"],["exclude","include"]]

c = 0
random.shuffle(quizwords)
for i in range(len(quizwords) - 1)[::2]:
    first_pair = quizwords[i]
    second_pair = quizwords[i+1]
    print(f'{first_pair[0]} is to {first_pair[1]} as {second_pair[0]} is to...')
    ans = input()

由于您已经在 for 循环中遍历列表中的项目，因此执行两级索引就是提取每个单词的第一个字母。
