Question

我最近发现了这段代码，但一直在努力弄清楚它是如何工作的。＆＃34; 111.txt＆＃34;是一个包含列表行的文本文件，其中每行的列表的第一部分是解决方案，该列表中的相应单词是与该解决方案相关的关键词。除了第8行（solutions[i[-1]] ...）之外，我理解其中的大部分内容。我一直在查找使用的不同模块，但我仍然不了解该行的作用及其工作原理。我是使用Python的新手，所以如果可能的话，我真的很感激这条线的简单解释。

提前致谢！

questionbank = []
with open ('111.txt') as questions:
    for line in questions:
        questionbank.append(line.strip().split(','))

solutions = {}
for i in questionbank:
    solutions[i[-1]] = i[0:len(i)-1]

def phone_problem():
    n = 2
    while n <3:
        problem = input("Phone problem?")
        for d,v in solutions.items():
            if any(word in problem for word in v):
                print(d)
                n = 4
            else:
                continue

phone_problem()

＆＃34; 112.txt＆＃34;的例子：

put your phone is rice, wet, damp, water, puddle
replace you screen, screen, crack, smash, shatter...

更新：我已经添加了您的代码，但它仍然没有输出解决方案。它只是继续运行while循环，无论我输入什么作为问题。我真的不确定为什么，但是当你定义解决方案时可能会这样做。

答案在下面的评论中......

solutions = {}
for i in questionbank:
    # i = ['put your phone is rice', 'wet', 'damp', 'water', 'puddle']
    # i[-1] means last thing in list = 'puddle'
    # i[0:len(i)-1] means everything in i except the last element
    #               which could be rewritten as i[:-1]
    solutions[i[-1]] = i[0:len(i)-1]
    # solutions['puddle'] = ['put your phone is rice', 'wet', 'damp', 'water']

我认为代码是错误的。难道解决方案的密钥不应该是该行的第一个元素吗？代码可以更好地编写如下。

solutions = {question[0]:question[1:] for question in questionbank}

def phone_problem():
    while True:
        problem = input("Phone problem?")
        for solution, key_words in solutions.items():
            if any(word in problem for word in key_words):
                print(solution)
                return

提取文本文件中的第一个单词，然后提取相应的单词？
