Working with Indexes

Having covered creating various types of pandas indexes, let's now examine several common patterns of use for these indexes. Specifically, we will examine:

• Creating and using an index with a Series or DataFrame
• Means of selecting values with an index
• Moving data to and from the index
• Reindexing a pandas object
