Python Pandas Tutorial 22 | How to Process Hierarchical Index

Hi guys...in this python pandas tutorial video I have talked about how you can work with hierarchical index and process the data based on multilevel hierarchies that are present in the pandas series or dataframe. I have mainly discuss how you can rename the index, how you can swap the indexes, how you unstack the index to create a dataframe, how you can select the nested index hierarchies for the selection of data and finally how you can do sum at various level of index hierarchy.
