From the earliest version in the late 1980s to the current version, it has evolved with the same philosophy: providing a multi-paradigm programming language with readability and productivity in mind.
People used to see Python as yet another scripting language and wouldn't feel right about using it to build large systems. But through the years and thanks to some pioneer companies, it became obvious that Python could be used to build almost any kind of a system.
In fact, many developers that come from another language are charmed by Python and make it their first choice.
This is something you are probably aware of if you have bought this book, so there's no need to convince you about the merits of the language any further.
