(1) a preliminary study of Python

This chapter describes the basic framework of Python and How to Run python.Program.

Python is often defined as an object-oriented scripting language and often serves as shell tools and control tools (distributed in large applications ).

She is object-oriented and free of charge and can be used for system programming, Gui programming, network scripting, component synthesis, database programming, game programming and AI.

Python program composition structure: a program consists of function modules, which contain statements, statements, expressions, expression generation, and object processing.

It can also be understood as follows: a process-oriented program consists of function modules, including data types, expressions, and flow control statements.

The script language does not need to be compiled and then executed every time and does not generate binary data.CodeYou can access the running program during execution, or even modify it dynamically. It is suitable for fast development of simple tasks. Python provides a large number of flexible data types and a wide range of computing types. Modular structure design and support for object-oriented technology; flexible package organization and a large number of class libraries.
