>> from past.builtins import str as oldstr
>>> philosopher = oldstr(u'孔子'.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]
'å'
>>> type(philosopher[0])
>>> # 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? ')
What is your name? [cursor]
>>> from past.builtins import reload
>>> reload(mymodule) # equivalent to imp.reload(mymodule) in Python 3
>>> from past.builtins import xrange
>>> for i in xrange(10):
... pass
It also provides import hooks so you can import and use Python 2 modules like
this::
$ python3
>>> from past.translation import autotranslate
>>> authotranslate('mypy2module')
>>> import mypy2module
until the authors of the Python 2 modules have upgraded their code. Then, for
example::
>>> mypy2module.func_taking_py2_string(oldstr(b'abcd'))
