Python 3: A Step-by-Step Guide to Learn, in an Easy Way, the Fundamentals of Python Programming Language

The goals of this book

• Cover programming topics as well as Python . Traditional textbooks do a pretty good job of teaching the basics of a given programming language, but they often do not cover relevant programming topics that are incidental to the language. For example, books will omit sections on programming style, common pitfalls, debugging, good/bad programming practices, and testing. Consequently, by the time you finish the book, you may understand how to program in a language, but you might also have picked up bad habits that will come back to bite you later! One of the goals of these tutorials is to make sure that all of these incidental topics are covered along the way, in the sections where it naturally makes sense to discuss them. When you finish, you will not only know how to program in Python , you will know how NOT to program in Python , which is arguably as important.
• Provide a lot of examples. Most people learn as much or more from following the examples as they do from reading the text. These tutorials will endeavor to provide plenty of clear, concise examples to show how to apply the concepts you are learning. We will also avoid (as much as possible) the twin evils: the magic hand wave (also known as …), where in the interest of space part of an example is omitted, and the unexplained new concept, where a new concept that is integral to the example is introduced without any mention of what it is or how it works. Both of these tend to lead to getting stuck.
• Provide practice programs. The end of many lessons and sections will contain some exercises that you can attempt to answer on your own, along with solutions. You can compare your solution against ours to see what we did differently, or, if you get stuck, how we solved the problem. Then you can go back and refocus on the areas you need more work on.
• Most importantly: have fun. Programming can be a lot of fun, and if you’re not generally having fun, you’re not in the right mindset to be programming. Tired or unhappy programmers make mistakes, and debugging code tends to take much longer than writing it correctly in the first place! Often you can save yourself some time by going to bed, getting a good night’s sleep, and coming back to a problem in the morning.
