Numerical Computing with Python

How to do it...

1. Read in the college dataset with the institution name as the index, and select a single column as a Series with the indexing operator:

>>> college = pd.read_csv('data/college.csv', index_col='INSTNM')>>> city = college['CITY']>>> city.head()INSTNM
Alabama A & M University                   Normal
University of Alabama at Birmingham    Birmingham
Amridge University                     Montgomery
University of Alabama in Huntsville    Huntsville
Alabama State University               Montgomery
Name: CITY, dtype: object

2. The .iloc indexer makes selections only by integer location. Passing an integer to it returns a scalar value:

>>> city.iloc[3]Huntsville

3. To select several different integer locations, pass a list to .iloc. This returns a Series:

>>> city.iloc[[10,20,30]]
