Pandas slicing along multiindex and separate indices

Question

I\'ve started using Pandas for some large Datasets and mostly it works really well. There are some questions I have regarding the indices though

1. I have a MultiI

Answer 1

For the first part, you can use boolean indexing using get_level_values:

df[df.index.get_level_values('a').isin([5, 7, 10, 13])]

For the second two, you can inspect the MultiIndex object by calling:

df.index

(and this can be inspected/sliced.)
