python - 将字典值替换为另一个字典值

Question

我有两个字典，First_Dict 和 Second_Dict:

First_Dict = {'Texas': 'Austin', 'California': 'San Diego', 'Florida': 'Miami', 
             'Arizona': 'Phoenix'}

Second_Dict = {'Family1': ['This family went to Arizona.'], 'Family2': ['This 
family went to Texas.'], 'Family3': ['This family went to California.']}

目标:对于 Second_Dict 中提到的每个状态，我需要将该值与 First_Dict 上的键相匹配。如果存在匹配项，请将 Second_Dict 的值替换为 First_Dict 键中的值。

所以输出将如下所示:

Second_Dict = {'Family1': ['This family went to Phoenix.'], 'Family2': 
          ['This family went to Austin.'], 'Family3': ['This family went to 
            San Diego.']}

我被这个问题难住了。非常感谢您的指导!

Answer 1

尝试字典理解:

import re
print({k:[' '.join([First_Dict.get(re.sub('[^a-zA-Z]','',i),i) for i in v[0].split()])+'.'] for k,v in Second_Dict.items()})

输出:

{'Family1': ['This family went to Phoenix.'], 'Family2': ['This family went to Austin.'], 'Family3': ['This family went to San Diego.']}

更新:

Second_Dict = {k:[' '.join([First_Dict.get(re.sub('[^a-zA-Z]','',i),i) for i in v[0].split()])+'.'] for k,v in Second_Dict.items()}

现在 Second_Dict 是字典，

所以:

print(Second_Dict)

是:

{'Family1': ['This family went to Phoenix.'], 'Family2': ['This family went to Austin.'], 'Family3': ['This family went to San Diego.']}
