提取文本文件中的第一个单词，然后提取相应的单词？

Question

我最近发现了这个代码，但一直在努力研究它是如何工作的。 “111.txt”是一个带有列表行的文本文件，其中每行上的列表的第一部分是解决方案，该列表中的相应单词是解决方案的关键词。我了解除了第8行（solutions[i[-1]] ...）之外的大部分内容。我一直在查找使用的不同模块，但我仍然不明白该线路是什么以及它是如何工作的。我对Python的使用很新，所以如果可能的话，我会非常感谢这一行的简单解释。

在此先感谢！

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() 

“112.txt” 的例子：

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

更新： 我在你的代码添加了，但它仍然简化版，输出的解决方案。无论我输入什么问题，它都会继续运行while循环。我真的不确定为什么，但当您定义解决方案时可能会这样做。

    other() 
keyList = list(set(keyList)) 
for i in keyList: 
    print("Solution:",i) 

Answer 1

答案就在下面的评论...

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'] 

我认为该代码是马车。解决方案的关键不应该是该行的第一个元素？代码可以写得更好，如下所示。

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
