如何通过使用查询删除行

Question

我正在尝试根据查询结果删除行，但这给了我这个错误

  df2.drop(df.query('group == "treatment" and landing_page !="new_page" or group != "treatment" and landing_page =="new_page"'),axis=1)

显示的错误是

ValueError: labels ['user_id' 'timestamp' 'group' 'landing_page' 'converted'] not contained in axis

Answer 1

将index输出中的query与axis=0一起用于以下行：

df2.drop(df.query('group == "treatment" and landing_page !="new_page" or group != "treatment" and landing_page =="new_page"').index, axis=0)
