Introduction to the Python standard library

The Python syntax and semantics are described in the Python Language Reference manual , and this manual introduces the content and use of the Python Standard library, Some of the optional component libraries in the release library are also described.

The Python standard library includes a wide range of content, which can be clarified by the folder length and content of the standard library.

The standard library includes modules that are written in C language. For example , the file functions of the system I/O are not directly visited by Python developers. These modules are therefore designed as built-in modules. In addition, the standard library provides developers with features that are often used by people. This can be a standard solution to improve developer speed and code quality. Other functional modules in the standard library are designed to improve portability. Encapsulate some system-specific APIs into a common interface. This also allows all of the Python that is written to be highly portable.

In the version number of the Python installation in Windows , the modules for the entire standard library are included. Other optional modules are also available.

In Unix -like systems. The installation only provides a subset of the feature packs, and the other parts of the standard library need to use the installation tool to choose which parts of the library you need to install.

In addition to the standard library, there are very versatile libraries that are not placed in this standard library. And it's constantly being added.

For example, some standalone programs, modules, or complete application frameworks can be used to derive these capabilities from the following connections:
