按索引从Pandas系列中删除元素 [英] Drop Elements from Pandas Series by Index

问题描述

我有一个熊猫系列df(日期=索引):

I have a pandas series df (dates = index):

2015-09-10     58
2015-09-11     40
2015-09-12     33
2015-09-13     42
2015-09-14     22
2015-09-15     88
2015-09-16     99
2015-09-17    124

我想将日期从2015-09-11拖放到2015-09-15，所以我的df如下所示:

I'd like to drop the dates from 2015-09-11 to 2015-09-15, so my df would look like:

2015-09-10     58
2015-09-16     99
2015-09-17    124

我尝试使用df.drop ["2015-09-11":"2015-09-15"]，但出现错误:

I've tried using df.drop["2015-09-11":"2015-09-15"], but i get an error:

TypeError: 'instancemethod' object has no attribute '__getitem__'

有什么建议吗?

谢谢！

推荐答案

尝试一下:

s = pd.Series([58,40,33,42,22,88,99,124], index =["2015-09-10","2015-09-11","2015-09-12","2015-09-13","2015-09-14","2015-09-15","2015-09-16","2015-09-17"])

In [140]: s
Out[140]:
2015-09-10     58
2015-09-11     40
2015-09-12     33
2015-09-13     42
2015-09-14     22
2015-09-15     88
2015-09-16     99
2015-09-17    124
dtype: int64

s.drop(s["2015-09-11":"2015-09-15"].index)

In [142]: s.drop(s["2015-09-11":"2015-09-15"].index)
Out[142]:
2015-09-10     58
2015-09-16     99
2015-09-17    124
dtype: int64
