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，我都需要将该值与First_Dict上的键匹配。如果存在匹配项，请用Second_Dict键中的值替换First_Dict的值。

所以输出看起来像这样：

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

我对此很困惑。指导手将不胜感激！

Answer 1

尝试dict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()}

然后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.']}

从另一个字典值替换字典值
