Numerical Computing with Python

How to do it...

1. Read in the names dataset, and output it:

>>> names = pd.read_csv('data/names.csv')>>> names

2. Let's create a list that contains some new data and use the .loc indexer to set a single row label equal to this new data:

>>> new_data_list = ['Aria', 1]>>> names.loc[4] = new_data_list>>> names

3. The .loc indexer uses labels to refer to the rows. In this case, the row labels exactly match the integer location. It is possible to append more rows with non-integer labels:

>>> names.loc['five'] = ['Zach', 3]>>> names
