Pandas 如果匹配字符串則刪除行（不區分大小寫）

Question

我正在嘗試刪除 dataframe 中的行，如果它包含我的列表中的某些內容。

東風

Search_List = ['drunk', 'owner']
df = df[~df['Searches'].str.contains('|'.join(Search_List))]

Searches
the person was Drunk
the owner was not available
This is a test
The Owner was not in

當前結果：

Searches
the person was Drunk
This is a test
The Owner was not in

預期結果：

Searches
This is a test

有沒有辦法進行搜索，但即使它是大寫等也允許它匹配？ 我無法將其轉換為較低然后進行搜索，因為它破壞了我在腳本中的其他功能。 有一個簡單的解決方案嗎？

Answer 1

將case=False參數添加到Series.str.contains ：

Search_List = ['drunk', 'owner']
df = df[~df['Searches'].str.contains('|'.join(Search_List), case=False)]
print (df)
         Searches
2  This is a test

Answer 2

您可以在檢查之前將字符串轉換為lowercase 。

df = df[~df['Searches'].str.lower().str.contains('|'.join(Search_List))]
