如何从Pandas数据框中删除行列表? [英] How to drop a list of rows from Pandas dataframe?

问题描述

我有一个数据框df:

>>> df
                  sales  discount  net_sales    cogs
STK_ID RPT_Date                                     
600141 20060331   2.709       NaN      2.709   2.245
       20060630   6.590       NaN      6.590   5.291
       20060930  10.103       NaN     10.103   7.981
       20061231  15.915       NaN     15.915  12.686
       20070331   3.196       NaN      3.196   2.710
       20070630   7.907       NaN      7.907   6.459

然后我要删除具有列表中指示的某些序列号的行，假设这里是[1,2,4],然后离开:

Then I want to drop rows with certain sequence numbers which indicated in a list, suppose here is [1,2,4], then left:

                  sales  discount  net_sales    cogs
STK_ID RPT_Date                                     
600141 20060331   2.709       NaN      2.709   2.245
       20061231  15.915       NaN     15.915  12.686
       20070630   7.907       NaN      7.907   6.459

如何或什么功能可以做到这一点?

How or what function can do that ?

推荐答案

使用 DataFrame.drop 并传递给它一系列索引标签:

Use DataFrame.drop and pass it a Series of index labels:

In [65]: df
Out[65]: 
       one  two
one      1    4
two      2    3
three    3    2
four     4    1


In [66]: df.drop(df.index[[1,3]])
Out[66]: 
       one  two
one      1    4
three    3    2
