It's possible to access single values of a Series:
>>> fruits = ['peaches', 'oranges', 'cherries', 'pears']
>>> S = pd.Series([20, 33, 52, 10], index=fruits)
>>> S['peaches']
20
We can also access more than one value by using a list of indices:
>>> S[['peaches', 'cherries', 'oranges']]
peaches 20
cherries 52
oranges 33
