Series operations

There exist a vast number of operators in Python for manipulating objects. For instance, when the plus operator is placed between two integers, Python will add them together:

>>> 5 + 9  # plus operator example. Adds 5 and 9
14

Series and DataFrames support many of the Python operators. Typically, a new Series or DataFrame is returned when using an operator.

In this recipe, a variety of operators will be applied to different Series objects to produce a new Series with completely different values.

How to do it…

1. Select the imdb_score column as a Series:

   >>> movies = pd.read_csv("data/movie.csv")
   >>> imdb_score = movies["imdb_score"]
   >>> imdb_score
   0       7.9
   1       7.1
   2       6.8
   3       8.5
   4       7.1
          ... 
   4911    7.7
   4912    7.5
   4913    6.3
   4914    6.3
   4915    6.6
   Name: imdb_score, Length: 4916, dtype: float64
   

2. Use the plus operator...
