ninja: many operations are faster on pre-aligned data. Adding two unaligned DataFrames internally triggers a reindexing step. For exploratory analysis you will hardly notice the difference (because reindex names. # Build MultiIndex In [304]: idx = pd.MultiIndex.from_tuples([('a', 1), ('a', 2), ('a', 2), .....: ('b', 2), ('b', 1), ('b', 1)]) .....: In [305]: idx.names = ['first', 'second'] # Build DataFrame includes information on the field names, types, and other attributes. You can use the orient table to build a JSON string with two fields, schema and data. In [267]: df = pd.DataFrame({'A': [1, 2, 3], ...
