Indexing, Slicing and Subsetting DataFrames in Python - Data Carpentry

In Python, portions of data can be accessed using indices, slices, column headings, and condition-based subsetting. Python uses 0-based indexing, in which the first element in a list, tuple or any other data structure has an index of 0. Pandas enables common data exploration steps such as data indexing, slicing and conditional subsetting.
