Retrieve the flattened underlying data of a Series

Overview:

The underlying data storage in the pandas classes, Series and DataFrame is the type numpy.ndarray.
The instance method ravel() returns the flattened underlying data for a panads Series object.
This method is often useful when sending data to interfaces where a pandas Series is not accepted, but a numpy ndarray is accepted.

# Example Python program that retrieves the underlying ndarray

import pandas as pds

numberList = [50, 60, 70, 80, 90];

numberSeries = pds.Series(numberList);

underlying = numberSeries.ravel();

print("Data present in the pandas Series:");

print(numberSeries);

print("Data as the ndarray:");

print(underlying);

print(type(underlying));

Data present in the pandas Series:

0 50

1 60

2 70

3 80

4 90

dtype: int64

Data as the ndarray:

[50 60 70 80 90]
