Performing numerical methods on pandas objects

pandas provides a rich set of functions and operations that facilitate the ability to perform arithmetic operations and to calculate various numerical characteristics of data. In this section, we will examine many of these, including:

• Performing arithmetic on a DataFrame or Series
• Getting the counts of values
• Determining unique values (and their counts)
• Finding minimum and maximum values
• Locating the n-smallest and n-largest values
• Calculating accumulated values

Performing arithmetic on a DataFrame or Series

Arithmetic operations can be performed on a DataFrame (and Series) using the +, -, /, and * operators. While these may seem trivial in nature, pandas adds a powerful twist...
