【问题描述】：

我有一本类似的字典：

countries = ["usa", "france", "japan", "china", "germany"]
fruits = ["mango", "apple", "passion-fruit", "durion", "bananna"]

cf_dict = {k:v for k,v in zip(["countries", "fruits"], [countries, fruits])}

我也有一个类似这样的字符串列表：

docs = ["mango is a fruit that is very different from Apple","I like to travel, last year I was in Germany but I like France.it was lovely"]

我想检查docs并查看每个字符串是否包含cf_dict中任何列表（cf_dict的值是列表）中关键字的any，如果它们存在则返回相应的@该字符串（文档中的字符串）的 987654326@（基于值）作为输出。

例如，如果我检查列表 docs，输出将是 [fruits, countries]

类似于answer 的东西，但它只检查一个列表，但是，我想检查多个列表。

【解决方案1】：

如果字符串匹配多个列表中的值（例如，'apple grows in USA' 应映射到 {'fruits', 'countries'}），则以下内容返回集合的字典。

print({s: {k for k, l in cf_dict.items() for w in l if w in s.lower()} for s in docs})

这个输出：

{'mango is a fruit that is very different from Apple': {'fruits'}, 'I like to travel, last year I was in Germany but I like France.it was lovely': {'countries'}}
