我有一个如下所示的熊猫数据框：-

我也有一个类似下面的列表：-

my_list = ['Launch', 'Dance', 'Issue']

使用以下命令可以过滤出数据框：-

 ndata = data[data['Tweets'].str.contains( "|".join(my_list), regex=True)].reset_index(drop=True)

如果我有

，则过滤器不起作用

    Working        Not Working
    Launch        'launch' , 'launch,' , 'Launch,' ,'LAUNCH','@launch'

预期的输出应为以下任何一个单词的句子

'launch' , 'launch,' , 'Launch,' ,'LAUNCH','@launch'

Answer 1

您需要确保contains忽略大小写：

import re

.
.
.

ndata = data[data['Tweets'].str.contains("|".join(my_list), regex=True,                          
                                         flags=re.IGNORECASE)].reset_index(drop=True)
#                                        ^^^^^^^^^^^^^^^^^^^

按列表过滤字符串列而不进行完全匹配
