Solution: Create a Customer Relationship Management System

Explore how to build a Customer Relationship Management system with Python by creating and refactoring Customer and Interaction classes. Understand the use of namedtuples, dataclasses, defaultdicts, queues, priority queues, dictionaries, and sets to manage and analyze customer data effectively.

We'll cover the following...

Create the original structure

Generate the Customer class incorporating id, name, and email attributes. Moreover, add another class named Interaction as well, containing customer_id, interaction_type, and timestamp attributes.

Python 3.10.4
class Customer:
  id: int
  name: str
  email: str
class Interaction:
  customer_id: int
  interaction_type: str
  timestamp: str

Refactor original classes

Now refactor the Customer class with named tuples and the Interaction class with dataclasses that help us to provide a convenient way to define classes with automatically generated methods. Moreover, refactor a dictionary to a ...
