Python for Everybody

This book assumes that everyone needs to know how to program, and that once you know how to program you will figure out what you want to do with your newfound skills.

While this book is not intended for professional programmers, professional programming can be a very rewarding job both financially and personally. Building useful, elegant, and clever programs for others to use is a very creative activity
