or:
def dict2str(d, preferred_order = ['gid', 'type', 'parent', 'name']):
pairs = [(item, d[item]) for item in preferred_order]
#preferred_order = set(preferred_order) # if preferred_order is big
pairs.extend(sorted((k, v) for k,v in d.iteritems() if k not in
preferred_order))
return '{%s}' % repr(pairs)[1:-1]
