The :mod:`operator` module exports a set of functions implemented in C
corresponding to the intrinsic operators of Python. For example,
Example: Build a dictionary that maps the ordinals from ``0`` to ``255`` to
their character equivalents.
- >>> import operator
>>> d = {}
>>> keys = range(256)
>>> vals = map(chr, keys)
- >>> map(operator.setitem, [d]*len(keys), keys, vals)
- [None, None, ..., None]
+ >>> map(operator.setitem, [d]*len(keys), keys, vals) # doctest: +SKIP
.. XXX: find a better, readable, example
method. Dictionaries accept any hashable value. Lists, tuples, and
strings accept an index or a slice:
- >>> from operator import itemgetter
>>> itemgetter(1)('ABCDEFG')
'B'
>>> itemgetter(1,3,5)('ABCDEFG')
