Learn Programming in Python with Cody Jackson

By: Cody Jackson

Overview of this book

Python is a cross-platform language used by organizations such as Google and NASA. It lets you work quickly and efficiently, allowing you to concentrate on your work rather than the language. Based on his personal experiences when learning to program, Learn Programming in Python with Cody Jackson provides a hands-on introduction to computer programming utilizing one of the most readable programming languages–Python. It aims to educate readers regarding software development as well as help experienced developers become familiar with the Python language, utilizing real-world lessons to help readers understand programming concepts quickly and easily. The book starts with the basics of programming, and describes Python syntax while developing the skills to make complete programs. In the first part of the book, readers will be going through all the concepts with short and easy-to-understand code samples that will prepare them for the comprehensive application built in parts 2 and 3. The second part of the book will explore topics such as application requirements, building the application, testing, and documentation. It is here that you will get a solid understanding of building an end-to-end application in Python. The next part will show you how to complete your applications by converting text-based simulation into an interactive, graphical user interface, using a desktop GUI framework. After reading the book, you will be confident in developing a complete application in Python, from program design to documentation to deployment.

SQLAlchemy

When working with databases, it can be difficult and time-consuming to deal with writing SQL queries all the time, especially if you don't deal with databases on a regular basis. Luckily, there are many Python libraries available to help with this problem. One of the most popular is SQAlchemy.

SQLAlchemy is an object-relational mapper (ORM), a utility that eliminates the issue of writing raw SQL queries and replaces it with more Python-centric code. ORM tools convert data between incompatible type systems in OOP languages, because these languages frequently use types that are more complex than low-level, primitive types. In other words, an ORM deals with more complex objects, whereas SQL expects primitives and creates relations between them.

Because SQLAlchemy is a third-party library, the easiest way to install it is through pip. pip is a standard Python package...
