Similar to NumPy
The Series object behaves similarly to a NumPy array. As shown below, both types respond to index operations:
Press + to interact
import numpy as npimport pandas as pdsongs3 = pd.Series([145, 142, 38, 13], name='counts', index=['Paul', 'John', 'George', 'Ringo'])numpy_ser = np.array([145, 142, 38, 13])print(songs3[1])print(numpy_ser[1])
They both have these methods in common:
Press + to interact
print(songs3.mean())print(numpy_ser.mean())
They also both have a notion of a boolean array. A boolean array is a Series with the same index as the Series we’re working with and has boolean values. It can be used as a mask to filter out items. Normal Python lists ...
