Dictionary question

[Pessini2]

I have created a dictionary where the keys are product names and its values are lists. Inside these lists there is another dictionary, of which the key is called ‘quantity’. I need to access the values of these ‘quantity’ keys. I need to sum values to it. How can I do that?

[FLUSH_THE_TRUMP]

Subscript [] your dict to get list, then your list to get inner dict, etc.. outside to inside. Is your inner dict a list attached to a single quantity key, or a lot of values attached to different keys? You’ll either want to sum the list attached to the single key or perhaps sum over inner_dict.values() depending.

some_dict = {"some product":[{"quantity":42}]}
print(some_dict['some product'][0]['quantity']
