如何从 pandas 数据框中选择的列表中检查值? [英] How to check if a value is in the list in selection from pandas data frame?

问题描述

看起来很丑:

df_cut = df_new[
             (
             (df_new['l_ext']==31) |
             (df_new['l_ext']==22) |
             (df_new['l_ext']==30) |
             (df_new['l_ext']==25) |
             (df_new['l_ext']==64)
             )
            ]

不起作用:

df_cut = df_new[(df_new['l_ext'] in [31, 22, 30, 25, 64])]

是否存在上述问题"的优雅且可行的解决方案?
