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.

Databases are popular for many applications, especially for use with web applications or customer-oriented programs. Databases are good when discrete structures are to be operated on, such as a customer list that has phone numbers, addresses, past orders, and so on. A database can store a lump of data and allow the user or developer to pull the necessary information, without regard to how the data is stored. Additionally, databases can be used to retrieve data randomly, rather than sequentially. For pure sequential processing, a standard file is better.

A database (DB) is simply a collection of data, placed into an arbitrary structured format. The most common DB is a relational database; tables are used to store the data and relationships can be defined between different tables. Structured Query Language (SQL) is the language used to work with most DBs. (SQL...
