来自当前df子集的新Pandas数据框

Question

I have a Pandas dataframe with town names in one column. I want to create a new dataframe containing a subset of those towns. I have tried the following code but it errors:

crime[(crime.Region == 'Stroud') & (crime.Region == 'Gloucester')]

The error I get is:

'Series' objects are mutable, thus they cannot be hashed.

Interestingly, this code works if I use '!=' and create a new dataframe based on stating the towns I do not want in it, however there are considerably more of these and it seems unintuitive.

Answer 1

我认为您正在寻找执行OR而非AND，因此您可能希望拥有类似

crime[(crime.Region == 'Stroud') | (crime.Region == 'Gloucester')]
