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.

Sets

Sets are unordered collections of hashable objects; in other words, each object is unique. Sets are commonly used to see if a collection of objects contains a particular item, remove duplicates from a sequence, and compute a variety of mathematical operations.

Sets look like dictionaries, in that curly braces {} are used to create a set. However, unlike dictionaries, sets only have values; there are no key names within a set.

The following example shows how to create a set:

knights_set = {"Sir Galahad", "Sir Lancelot", "Sir Robin"} 

Sets are also like dictionaries in that the objects they contain are unordered, and it is likely that calling a set will show a different order of objects compared to what was originally set.

There are actually two types of sets: set and frozenset. A regular set is mutable, in that it can be modified in-place. A frozenset...
