Here’s a hack that almost gives you the syntax you want:
class _OrderedDictMaker(object):
def __getitem__(self, keys):
if not isinstance(keys, tuple):
keys = (keys,)
assert all(isinstance(key, slice) for key in keys)
return OrderedDict([(k.start, k.stop) for k in keys])
ordereddict = _OrderedDictMaker()
from nastyhacks import ordereddict
menu = ordereddict[
"about" : "about",
"login" : "login",
'signup': "signup"
]
Edit: Someone else discovered this independently, and has published the odictliteral
package on PyPI that provides a slightly more thorough implementation – use that package instead
