按ip地址范围过滤Pandas DataFrame

Question

我需要Dataframe按ip地址范围过滤大熊猫.是否可以使用正则表达式？

Ex. From 61.245.160.0   To 61.245.175.255

Answer 1

字符串可以在python中订购,所以你应该能够逃脱:

In [11]: '61.245.160.0' < '61.245.175.255'
Out[11]: True

布尔掩码:

In [12]: df[('61.245.160.0' < df.ip) & (df.ip < '61.245.175.255')]

或者切片(如果ip是索引):

In [13]: df.loc['61.245.160.0':'61.245.175.255']
