Overview of this book

Python is a multipurpose language that can be used for multiple use cases. Python for Geeks will teach you how to advance in your career with the help of expert tips and tricks. You'll start by exploring the different ways of using Python optimally, both from the design and implementation point of view. Next, you'll understand the life cycle of a large-scale Python project. As you advance, you'll focus on different ways of creating an elegant design by modularizing a Python project and learn best practices and design patterns for using Python. You'll also discover how to scale out Python beyond a single thread and how to implement multiprocessing and multithreading in Python. In addition to this, you'll understand how you can not only use Python to deploy on a single machine but also use clusters in private as well as in public cloud computing environments. You'll then explore data processing techniques, focus on reusable, scalable data pipelines, and learn how to use these advanced techniques for network automation, serverless functions, and machine learning. Finally, you'll focus on strategizing web development design using the techniques and best practices covered in the book. By the end of this Python book, you'll be able to do some serious Python programming for large-scale complex projects.

Importing modules

Python code in one module can get access to the Python code in another module by a process called importing modules.

To elaborate on the different module and package concepts, we will build two modules and one main script that will use those two modules. These two modules will be updated or reused throughout this chapter.

To create a new module, we will create a .py file with the name of the module. We will create a mycalculator.py file with two functions: add and subtract. The add function computes the sum of the two numbers provided to the function as arguments and returns the computed value. The subtract function computes the difference between the two numbers provided to the function as arguments and returns the computed value.

A code snippet of mycalculator.py is shown next:

# mycalculator.py with add and subtract functions
def add(x, y):
    """This function adds two numbers"""
