Binary Data Services二进制数据服务

The modules described in this chapter provide some basic services operations for manipulation of binary data. 本章描述的模块提供了一些用于操作二进制数据的基本服务操作。Other operations on binary data, specifically in relation to file formats and network protocols, are described in the relevant sections.有关二进制数据的其他操作，特别是与文件格式和网络协议相关的操作，将在相关章节中介绍。

Some libraries described under Text Processing Services also work with either ASCII-compatible binary formats (for example, re) or all binary data (for example, difflib).文本处理服务中描述的一些库还可以使用ASCII兼容的二进制格式（例如re）或所有二进制数据（例如difflib）。

In addition, see the documentation for Python’s built-in binary data types in Binary Sequence Types — bytes, bytearray, memoryview.此外，请参阅二进制序列类型：bytes、bytearray、memoryview中Python内置二进制数据类型的文档。
