1. Using class keyword, define the class CosineSimilarity. 2. Define the _init__() function, which accepts three parameters, self, x, and z, and stores them as class variables. These two parameters will be the vectors used to compute the cosine similarity. 3. Create a function named compute angle() that accepts just self as an argument (remember self is a required argument for methods). 4. Within the compute angle() method compute the angle between two vectors and return the answer in degrees. Use the following equation to compute the angle between two vector. $$ \theta = \text{arccos}{\frac{\mathbf{x} \cdot \mathbf{z}} {||\mathbf{x}|| 2 ||\mathbf{z}|| 2}) $$

Object Oriented Programming System (OOPs) is a programming model built on the perception of “objects” that contains data and methods. The major purpose of Object Oriented Programming is to increase the maintainability and flexibility of programs. Object Oriented Programming gets together data and its behavior (methods) in a single location (object) which makes it easier to understand.
