 | Binary Data Services | 
 | ******************** | 
 |  | 
 | 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 :ref:`textservices` also work with either | 
 | ASCII-compatible binary formats (for example, :mod:`re`) or all binary data | 
 | (for example, :mod:`difflib`). | 
 |  | 
 | In addition, see the documentation for Python's built-in binary data types in | 
 | :ref:`binaryseq`. |
