It is a package manager that is both cross-platform and language agnostic (it can play a similar role to a pip and virtualenv combination). 5 pandas: underlying array is a numpy.ndarray. However, pandas and 3rd party libraries may extend NumPys type system to add support for custom arrays (see dtypes). To get the actual data inside a Index or Series,
