Akathorn Greyhat sent me by email the next solution, which althought
isn't generic it works well:
-------------
You could make your own class for that, maybe something like
#########
class MyCoolDictionary(dict):
def __init__(self, *args, **kargs):
dict.__init__(self, *args, **kargs)
def __getitem__(self, item):
try:
return dict.__getitem__(self, item)
except KeyError:
keys=[]
for i in dictio.keys():
if dictio[i]==item:
keys.append(i)
return keys
dictio=MyCoolDictionary({"a" : 1, "b" : 2, "c" : 2})
print dictio["a"]
print dictio["b"]
print dictio[1]
print dictio[2]
#########
The output of this code is:
1
2
['a']
['c', 'b']
Note that it isn't finish, maybe you'll need to make some kind of test
before adding a new value because with this code one value can have
multiple keys, and I have fixed it by returning a list of keys instead
a single value. It's up to you =)
I'm sorry of my poor english =(
