You may optionally enter a comparison operator (<, <=, >, >=, <> or =) at the beginning of each of your search values to specify how the comparison should be done.
# empty dict

# some static values

"key1" : {"item1":"value1"},
"key2" : {"itemX":"valueY"},
"keyX" : {"item99":"value98"}
}
# update a key programmatically
myDict.update({"key1" = {"item2":"new value"}})
# iterate
for (key, subdict) in myDict.items():
current_key = key
current_subdict = subdict
# get an specific item
subdict = myDict.get("key2")
print subdict.get("itemX")
# valueY
