Drop Elements from Pandas Series by Index
提问by jjjayn
I have a pandas series df (dates = index):
我有一个Pandas系列 df（日期 = 索引）：
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
I'd like to drop the dates from 2015-09-11 to 2015-09-15, so my df would look like:
我想将日期从 2015-09-11 删除到 2015-09-15，所以我的 df 看起来像：
2015-09-10 58
2015-09-16 99
2015-09-17 124
I've tried using df.drop["2015-09-11":"2015-09-15"], but i get an error:
我试过使用 df.drop["2015-09-11":"2015-09-15"]，但出现错误：
TypeError: 'instancemethod' object has no attribute '__getitem__'
Any advices?
有什么建议吗？
Thanks!
谢谢！

Try that:
试试看：
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
