- """
- A resurrection of some old functions from Python 2 for use in Python 3. These
- should be used sparingly, to help with porting efforts, since code using them
- is no longer standard Python 3 code.
- This module provides the following:
- 1. Implementations of these builtin functions which have no equivalent on Py3:
- - apply
- - chr
- - cmp
- - execfile
- 2. Aliases:
- - intern <- sys.intern
- - raw_input <- input
- - reduce <- functools.reduce
- - reload <- imp.reload
- - unichr <- chr
- - unicode <- str
- - xrange <- range
- 3. List-producing versions of the corresponding Python 3 iterator-producing functions:
- - filter
- - map
- - range
- - zip
- 4. Forward-ported Py2 types:
- - basestring
- - dict
- - str
- - long
- - unicode
