This module contains various constants relating to the intimate
details of the pickle module, some lengthy comments about
the implementation, and a few useful functions for analyzing pickled
data. The contents of this module are useful for Python core
developers who are working on the pickle and cPickle
implementations; ordinary users of the pickle module probably
won't find the pickletools module relevant.

pickle[, out=None, memo=None, indentlevel=4]) |
-
Outputs a symbolic disassembly of the pickle to the file-like object
out, defaulting to
sys.stdout. pickle can be a
string or a file-like object. memo can be a Python dictionary
that will be used as the pickle's memo; it can be used to perform
disassemblies across multiple pickles created by the same pickler.
Successive levels, indicated by MARK opcodes in the stream, are
indented by indentlevel spaces.
-
Provides an iterator over all of the opcodes in a pickle, returning a
sequence of
(opcode, arg, pos) triples.
opcode is an instance of an OpcodeInfo class; arg
is the decoded value, as a Python object, of the opcode's argument;
pos is the position at which this opcode is located.
pickle can be a string or a file-like object.
Release 2.4.2, documentation updated on 28 September 2005.
