在一个Python语句中使用字典一次更改多个关键字

Question

有没有办法像使用字典一样使用字典str.contains公司？你知道吗

我有一本字典，它看起来像这样：

A = {'Hey':1}

我知道对于字典，它会寻找精确的匹配（区分大小写和空格），所以我不知道是否有可能做到这一点。你知道吗

我的数据帧如下所示：

          Statements
0    Hey how are you?
1    Hey is their anyway to find that
2    Hey is their a way to prove this
3    over their, hey, how are you?

我想做的是使用我的字典，基本上检查语句中的每一行，如果字符串包含Hey，请将其更改为1，此外，如果我可以这样做，我想知道是否可以在字典中放入多个语句？像这样：

A={'Hey'、'Hello'、'Hi'：1}

我想做的是把一堆可能的字符串放入字典中，如果在语句中找到了这些字符串，那么根据需要进行更改。在本例中，Hey是语句中唯一会被更改的单词。你知道吗

我的预期结果如下：

          Statements
0    1 how are you?
1    1 is their anyway to find that
2    1 is their a way to prove this
3    over their, 1, how are you?

Answer 1

我认为您可以先创建dict of list，然后将keys与values交换为d和^{}：

L = ['Hey how are you?',
     'Hey is their anyway to find that',
     'Hey is their a way to prove this',
     'over their, hey, how are you?']

df = pd.DataFrame({'Statements':L})

A = {'1':['Hey', 'Hello', 'Hi', 'hey']}
d = {k: oldk for oldk, oldv in A.items() for k in oldv}
print (d)
{'Hi': '1', 'hey': '1', 'Hey': '1', 'Hello': '1'}

df['Statements'] = df['Statements'].replace(d, regex=True)
print (df)
                       Statements
0                  1 how are you?
1  1 is their anyway to find that
2  1 is their a way to prove this
3     over their, 1, how are you?
