7. 二进制数据服务

The modules described in this chapter provide some basic services operations for manipulation of binary data. Other operations on binary data, specifically in relation to file formats and network protocols, are described in the relevant sections.

Some libraries described under 文字处理服务 also work with either ASCII-compatible binary formats (for example, re) or all binary data (for example, difflib).

In addition, see the documentation for Python’s built-in binary data types in 二进制序列类型 — bytes, bytearray, memoryview.
