I want to remoeve rows that have this.我想删除有这个的行。

I have tries this but its not working我试过这个，但它不工作

df.loc[~(df['col_name'].str.contains('*'))]

Answer 1

Because * is special regex character add regex=False to Series.str.contains :因为*是特殊的正则表达式字符将regex=False添加到Series.str.contains ：

df.loc[~(df['col_name'].str.contains('*', regex=False))]

Or escape * :或转义* ：

df.loc[~(df['col_name'].str.contains('\*'))]
