Introduction to Python3
Python is a cross-platform computer programming language. It is an interpreted, object-oriented, and dynamic high-level programming language. It is used in many fields, including Web programming, scripting, scientific computing, and artificial intelligence.
Python was originally designed for writing automated scripts (shells), but as versions continue to be updated and new features are added to the language, it is increasingly being used for the development of independent, large projects.
There is no superior or inferior language, each has its own value, each programming language has its own advantages; C language can be used to write operating system is close to the hardware language, so, C language is suitable for the development of those who pursue speed, give full play to the hardware performance of the program. Python is a high-level programming language for writing applications.
2.1 Content Introduction
Python3 Is a guide to Python3 that covers the basics of Python, including language introduction, environment setup, program operation, basic syntax, and variables….. I have written a total of 10 chapters, which will be continuously updated (directly update the PDF in the resource pack). The screenshot is clear, the code is detailed, and all have coloring, which is convenient to read and run the test directly.
