Introduction to the Python standard library

Python 's syntax and semantics are described in the Python Language Reference manual , and this manual focuses on 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 contains a wide range of content, which can be understood through the catalog length and content of the standard library. The standard library contains modules that are written using the C language, such as file functions that Access system I/O , which are used in Python Developers are not directly accessible, so these modules are designed as built-in modules. In addition, the standard library provides developers with features that are often used so that they can become standard solutions that increase developer speed and code quality. There are also functional modules in the standard library designed to improve portability, encapsulating some of the system's proprietary APIs into a common interface, so that all written Python has a high level of portability.

In the Python installation version of Windows , the modules for the entire standard library are included, plus some other optional modules. In Unix -like systems, the installation provides only a subset of the feature packs, and the other parts of the standard library need to use the installation tools to select the parts of the library that you need to install.

In addition to the standard library, there are many feature libraries that are not placed in the standard library, and are still growing. For example, some standalone programs, modules, or complete application frameworks can be obtained from the following connections:
