Overview of this book

Learn Python Programming, Third Edition is both a theoretical and practical introduction to Python, an extremely flexible and powerful programming language that can be applied to many disciplines. This book will make learning Python easy and give you a thorough understanding of the language. You'll learn how to write programs, build modern APIs, and work with data by using renowned Python data science libraries. This revised edition covers the latest updates on API management, packaging applications, and testing. There is also broader coverage of context managers and an updated data science chapter. The book empowers you to take ownership of writing your software and become independent in fetching the resources you need. You will have a clear idea of where to go and how to build on what you have learned from the book. Through examples, the book explores a wide range of applications and concludes by building real-world Python projects based on the concepts you have learned.

Python's execution model

In this section, we would like to introduce you to some important concepts, such as scope, names, and namespaces. You can read all about Python's execution model in the official language reference (https://docs.python.org/3/reference/executionmodel.html), of course, but we would argue that it is quite technical and abstract, so let us give you a less formal explanation first.

Names and namespaces

Say you are looking for a book, so you go to the library and ask someone to obtain this. They tell you something like Second Floor, Section X, Row Three. So, you go up the stairs, look for Section X, and so on. It would be very different to enter a library where all the books are piled together in random order in one big room. No floors, no sections, no rows, no order. Fetching a book would be extremely hard.

When we write code, we have the same issue: we have to try and organize it so that it will be easy for someone who has no prior knowledge...
