Whereas ``future`` -contains backports of Python 3 constructs to Python 2, ``past`` provides -implementations of some Python 2 constructs in Python 3 and tools to import and -run Python 2 code in Python 3. It is intended to be used sparingly, as a way of -running old Python 2 code from Python 3 until the code is ported properly. - -Potential uses for libraries: - -- as a step in porting a Python 2 codebase to Python 3 (e.g. with the ``futurize`` script) -- to provide Python 3 support for previously Python 2-only libraries with the - same APIs as on Python 2 -- particularly with regard to 8-bit strings (the - ``past.builtins.str`` type). -- to aid in providing minimal-effort Python 3 support for applications using - libraries that do not yet wish to upgrade their code properly to Python 3, or - wish to upgrade it gradually to Python 3 style. - - -Here are some code examples that run identically on Python 3 and 2:: - - >>> from past.builtins import str as oldstr - - >>> philosopher = oldstr(u'\u5b54\u5b50'.encode('utf-8')) - >>> # This now behaves like a Py2 byte-string on both Py2 and Py3. - >>> # For example, indexing returns a Python 2-like string object, not - >>> # an integer: - >>> philosopher[0] - '\xe5' - >>> type(philosopher[0]) - <past.builtins.oldstr> - - >>> # List-producing versions of range, reduce, map, filter - >>> from past.builtins import range, reduce - >>> range(10) - [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] - >>> reduce(lambda x, y: x+y, [1, 2, 3, 4, 5]) - 15 - - >>> # Other functions removed in Python 3 are resurrected ... - >>> from past.builtins import execfile - >>> execfile('myfile.py') - - >>> from past.builtins import raw_input - >>> name = raw_input('What is your name?
