使用输入显示字典值

Question

我可以成功导入字典，并且可以从字典中获取其值的输出，但它会显示所有值，而不是与用户输入匹配的值。

输入首先被转换为低级，然后拆分成单个单词以在字典中引用。

# prob_dict : dictionary

# problemlist : input lowercase and split

我搜索了很多帖子，但找不到有效的解决方案。

problemlist = problem1.split()

for problem in range(len(prob_dict)):
    if prob_dict in problemlist:
        solution = []
        solution = (prob_dict[problem])
        print('Your Solution is:', solution)
    else:
        print('could not find a solution')

字典是：

prob_dict = {'wet': ['put in bag of rice to dry out'],
             'screen': ['screen will need to be replaced'],
             'charger': ['purchase new charger for our store']
             }

if prob_dict in problemlist 几乎不会发生。您不会在字符串列表中找到dict。

相反，您应该遍历列表中的项目并查看字典中是否包含该项目的键：

problemlist = [p.lower() for p in problem1.split()]

for problem in problemlist:
    if problem in prob_dict:
        print('Your Solution is: ', prob_dict[problem][0])
              #                                        ^ The associated string
        break # remember to break once solution is found
else:
    print('could not find a solution')
