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.

Python numbers

Python can handle normal long integers (the maximum length is determined based on the operating system, just like C), Python long integers (the maximum length is dependent on available memory), floating-point numbers (just like C doubles), octal and hexadecimal numbers, and complex numbers (numbers with an imaginary component).

Here are some examples of these numbers:

  • Integer: 12345, -32
  • Python integer: 999999999L (in Python 3.x, all integers are Python integers)
  • Float: 1.23, 4e5, 3e-4
  • Octal: 012, 0456
  • Hexadecimal: 0xf34, 0X12FA
  • Complex: 3+4j, 2J, 5.0+2.5j

Historically, integers were 16-bit numbers while longs were 32-bit. This could cause problems when using compiled languages, such as C, because trying to store a number that was too big for its data type could cause errors. The largest 16-bit number available is 65535, so trying to store 999999999 in a regular...
