python - 如何剪切特定单词后的字符串？

Question

我有一列文本。如何剪切每个文本在术语show less之后的部分？

例如:

df = pd.DataFrame({'col':['hi there see less new way is comming','today is summer, see less , is a lovely day']})

看起来像:

col 
'hi there see less new way is comming'
'today is summer, see less , is a lovely day'

输出:

col 
'hi there'
'today is summer,'

Answer 1

您可以使用str.split在see less上进行分割，然后使用str切片来获取第一部分。

df['col'] = df['col'].str.split('see less').str[0]

输出:

                 col
0          hi there 
1  today is summer,
