Chapter One introduction to Python language

What is 1.1 python?

Python (United Kingdom pronunciation:/?pa?θ?n/American pronunciation:/?pa?θɑ?n) What is it? Simply put, it is a computer programming language and a set of supporting software tools and libraries. is an object-oriented, interpreted computer programming language, invented by Guido van Rossum in 1989, and the first public release was released in 1991 [1].

Python is purely free software, and the source code and interpreter CPython follow the GPL (GNU general public License) agreement.

Python syntax is simple and clear, and one of the features is to force whitespace (white space) to be indented as a statement.

Python has a rich and powerful library. It is often nicknamed the glue language and is able to easily connect a variety of modules made in other languages, especially in C + +. A common application scenario is to use Python to quickly build a prototype of a program (sometimes even the final interface of the program) and then rewrite it in a more appropriate language, such as a graphics rendering module in a 3D game, with a particularly high performance requirement, and can be rewritten in C + + with a specially requested part. It is then encapsulated as an extension class library that Python can call. It is important to note that you may need to consider platform issues when you use the Extended class library, and some may not provide cross-platform implementations.

Application of 1.2 python

Well-received as a powerful and versatile programming language, Python has a very clear syntax and is suitable for a wide range of operating systems, and is now becoming more and more popular internationally.
