Accessing elements of Python dictionary by index

Question

Consider a dict like

mydict = {
  \'Apple\': {\'American\':\'16\', \'Mexican\':10, \'Chinese\':5},
  \'Grapes\':{\'Arabian\':\'25\',\'Indian\':\'20\'} }
         


        

Answer 1

As a bonus, I'd like to offer kind of a different solution to your issue. You seem to be dealing with nested dictionaries, which is usually tedious, especially when you have to check for existence of an inner key.

There are some interesting libraries regarding this on pypi, here is a quick search for you.

In your specific case, dict_digger seems suited.

>>> import dict_digger
>>> d = {
  'Apple': {'American':'16', 'Mexican':10, 'Chinese':5},
  'Grapes':{'Arabian':'25','Indian':'20'} 
}

>>> print(dict_digger.dig(d, 'Apple','American'))
16
>>> print(dict_digger.dig(d, 'Grapes','American'))
None
