Python is a great language for doing data analysis, primarily because of the fantastic ecosystem of data-centric Python packages. Pandas is one of those packages and makes importing and analyzing data much easier.
Series.add() is used to add series or list like objects with same length to the caller series.
Syntax: Series.add(other, level=None, fill_value=None, axis=0)
other: other series or list type to be added into caller series
fill_value: Value to be replaced by NaN in series/list before adding
level: integer value of level in case of multi index
Return type: Caller series with added values

In the following examples, the data frame used contains data of some NBA players. The image of data frame before any operations is attached below.
Example #1: Adding List
In this example, the top 5 rows are stored in new variable using .head() method. After that a list of same length is created and added to the salary column using
As shown in the output image, it can be compared that the Added value column is having the added values of Salary column + list.
Example #2: Adding series to series with null values
In this example, the Age column is added to the Salary column. Since the salary column contains null values too, by default it returns NaN no matter what is added. In this example, 5 is passed to replace null values with 5.
As shown in the output image, the Added value column has added age column with 5 in case of Null values.
