Consider a dict like
mydict = { \'Apple\': {\'American\':\'16\', \'Mexican\':10, \'Chinese\':5}, \'Grapes\':{\'Arabian\':\'25\',\'Indian\':\'20\'} }
Given that it is a dictionary you access it by using the keys. Getting the dictionary stored under "Apple", do the following:
>>> mydict["Apple"] {'American': '16', 'Mexican': 10, 'Chinese': 5}
And getting how many of them are American (16), do like this:
>>> mydict["Apple"]["American"] '16'
