a question on the new dict() keyword argument syntax

Hi,

Is there an equivalent keyword argument syntax for these cases:

d1 = {1:"one"}

d2 = {"1":"one"}

these don't work, of course:
a = dict(1 = "one") SyntaxError: keyword can't be an expression
a = dict("1" = "one")

SyntaxError: keyword can't be an expression

Just curious...

As you discovered, there is no equivalent. The new
syntax is limited to strings that are valid identifiers
(variable names).

Imagine I have a dict looking something like this: myDict = {"key 1": , "key 2": , "key 3": , "key 4": } That is, a set of keys which have a variable length list of associated values after them. What I want to do is filter out a subset of this dict to produce another dict that satisfies a set of criteria (in this case whether it contains all four values) to end up with something

I'd like to subclass dict to disallow overwriting of keys, something like: >>> class SafeDict(dict): .... def __setitem__(self, key, value): .... if key in self: .... raise KeyError('cannot assign value %r to key %r, value %r' .... 'already exists' % (value, key, self)) .... super(SafeDict, self).__setitem__(key, value) ....

Although I realize the perils of even suggesting polluting the Python namespace with a new keyword, I often think that it would be useful to consider defining an operator for testing whether or not an item is a member of a category. Currently, we have the 'in' operator, which tests for membership within a container, and that works very well -- in particular, it allows such membership tests to be expressed in very natural way. So for...

If I have a collection of dicts like: john = {'id': 1, 'name': "John Cleese", 'year': 1939} graham = {'id': 2, 'name': "Graham Chapman", 'year': 1941} I could store all of them in a list. But for easy lookup, I might store all these in a dict instead, like people = {'1': john, '2': graham}

Although I consider dict(**kwds) as one of the few unfortunate design choices in python since it prevents the future addition of useful keyword arguments (e.g a default value or an orderby function), I've been finding myself lately using it sometimes instead of dict literals, for no particular reason. Is there any coding style consensus on when should dict literals be preferred over dict(**kwds) and vice versa ? George
