| Interface | Description | 
|---|---|
| PyIOFile | PyIOFiles encapsulates and optimise access to the different file
representation. | 
| Class | Description | 
|---|---|
| _bytecodetools | BytecodeTools provides tools for generated JVM bytecode. | 
| _codecs | This class corresponds to the Python _codecs module, which in turn lends its functions to the
 codecs module (in Lib/codecs.py). | 
| _codecs.EncodingMap | Optimized charmap encoder mapping. | 
| _hashlib | The Python _hashlib module: provides hashing algorithms via
 java.security.MessageDigest. | 
| _hashlib.Hash | A generic wrapper around a MessageDigest. | 
| _imp | |
| _marshal | |
| _marshal.Marshaller | |
| _marshal.Unmarshaller | |
| _py_compile | |
| _sre | |
| _systemrestart | |
| ArrayModule | The python array module, plus jython extensions from jarray. | 
| binascii | The binascii.java module contains a number of methods to convert
 between binary and various ASCII-encoded binary
 representations. | 
| cmath | |
| cPickle | From the python documentation:
 
 The cPickle.java module implements a basic but powerful algorithm
 for ``pickling'' (a.k.a. serializing, marshalling or flattening) nearly
 arbitrary Python objects. | 
| cPickle.Pickler | The Pickler object | 
| cPickle.Unpickler | The Unpickler object. | 
| cStringIO | This module implements a file-like class, StringIO, that reads and
 writes a string buffer (also known as memory files). | 
| cStringIO.StringIO | The StringIO object | 
| errno | The Python errno module. | 
| gc | 
 In Jython, the gc-module notably differs from that in CPython. | 
| gc.CycleMarkAttr | |
| jarray | |
| math | |
| math_erf | |
| math_gamma | |
| operator | |
| PyIOFileFactory | |
| PyStruct | |
| PyStructDerived | |
| Setup | |
| SHA224Digest | SHA-224 as described in RFC 3874. | 
| struct | This module performs conversions between Python values and C
 structs represented as Python strings. | 
| synchronize | |
| synchronize.SynchronizedCallable | |
