##1.1 What is Python

I believe that many friends in the IT industry know that Python is one of the hottest topics in recent years. In terms of nature, it is not fundamentally different from the well-known C, Java, PHP, etc. It is also a development language, and has advanced to the top 5 of more than 20 mainstream development languages ​​(data comes from the latest TIOBE ranking list).

1.2 The origin and development trend of Python

The past life of Python originated from the originator "Uncle Turtle". In 1989, Guido van Rossum decided to develop a new script interpreter to kill a boring Christmas in Amsterdam. Since then, Python and its founder "Uncle Turtle" have entered the public eye. He hopes that this new language called Python can meet his ideal: to create a language between C and shell that is comprehensive, easy to learn, easy to use, and scalable.

In 1991, the first Python compiler was born. It is implemented based on C language and can call C language library files. After successive versions and innovations, Python reached a very milestone node, that is, version 2.4 in 2004 gave birth to the most popular WEB framework Django! Six years later, Python has developed to version 2.7, which is the latest and more widely used version of the 2.x version so far.

The birth of the 2.7 version is different from the vertical replacement logic of the previous 2.x version. It is a bridge between the 2.x version and the 3.x version in order to maximize the Inherit the new features of version 3.x while trying to maintain compatibility with 2.x.

Therefore, version 3.x has come out before version 2.7. Starting from version 3.0 in 2008, the python3.x system has been developing rapidly, with active version updates, and has been developing to The latest version is now 3.5.2. Version 3.5 is also the mainstream and widely used version in the current 3.x series. The demos of subsequent related programs are all based on version 3.5 by default.
