Python (British pronunciation: /ˈpaɪθən/ American pronunciation: /ˈpaɪθɑːn/) is an object-oriented interpreted computer programming language invented by the Dutch Guido van Rossum in 1989. The first public release was released in 1991 .
Python is purely free software. The source code and interpreter CPython follow the GPL (GNU General Public License) agreement. Python syntax is concise and clear, and one of its features is the mandatory use of white space as statement indentation.

Python has rich and powerful libraries. It is often nicknamed the glue language, which can easily connect various modules made in other languages ​​​​(especially C/C). A common application situation is to use Python to quickly generate a prototype of the program (sometimes even the final interface of the program), and then rewrite the parts with special requirements in a more suitable language, such as the graphics rendering module in 3D games. If the performance requirements are particularly high, it can be rewritten in C/C and then encapsulated into an extended class library that can be called by Python. It should be noted that you may need to consider platform issues when using extended class libraries, and some may not provide cross-platform implementation.
