Transitioning to Python 3

The Python language, which is not new but continues to gain momentum and users as if it were, has changed remarkably little since it first was released. I don’t mean to say that Python hasn’t changed; it has grown, gaining functionality and speed, and it’s now a hot language in a variety of domains, from data science to test automation to education. But, those who last used Python 15 or 20 years ago would feel that the latest versions of the language are a natural extension and evolution of what they already know.
