Overview of this book

After a brief history of Python and key differences between Python 2 and Python 3, you'll understand how Python has been used in applications such as YouTube and Google App Engine. As you work with the language, you'll learn about control statements, delve into controlling program flow and gradually work on more structured programs via functions. As you settle into the Python ecosystem, you'll learn about data structures and study ways to correctly store and represent information. By working through specific examples, you'll learn how Python implements object-oriented programming (OOP) concepts of abstraction, encapsulation of data, inheritance, and polymorphism. You'll be given an overview of how imports, modules, and packages work in Python, how you can handle errors to prevent apps from crashing, as well as file manipulation. By the end of this course, you'll have built up an impressive portfolio of projects and armed yourself with the skills you need to tackle Python projects in the real world.

Section 4
Using main ()
Most other programming languages (for example, Java and C++) require a special function, called main(), which tells the operating system what code to execute when a program is invoked. This is not necessary for Python, but in this section, you will find that it is a good and logical way to structure a program.
