Separate nested python dictionary into 2 separate dictionaries - python-2.7

Question

So I have a nested dictionary in python as follows:
{'name': 'Waffles',
'subCategories': [{'menu': [{'name': 'Fig & Honey with Fresh Cream','price': 120},
{'name': 'Toffeed Banana', 'price': 110}],
'name': 'Sweet',
'description': 'Sweet and yummy'},
{'menu': [{'name': 'Mushroom Cheese Gratin','price': 175},
{'name': 'Pepper Chicken Waffle', 'price': 180}],
'name': 'Savoury'
'description' : 'Salty and yummy'}]
}
What I am looking at is to separate out the dict into 2 dicts as follows:
{'name': 'Waffles(Sweet)',
'menu': [{'name': 'Fig & Honey with Fresh Cream','price': 120},
{'name': 'Toffeed Banana', 'price': 110}],
'description' : 'Sweet and yummy'}
{'name': 'Waffles(Savoury)',
'menu': [{'name': 'Mushroom Cheese Gratin','price': 175},
{'name': 'Pepper Chicken Waffle', 'price': 180}],
'description': 'Salty and yummy'}
Note that the name key is a combination of the same key in the outer and inner dicts
What would be the best way to tackle this ?

Answer 1

Hoping the code is self explantory!!
import pprint
d = {'name': 'Waffles',
'subCategories': [
{'menu': [{'name': 'Fig & Honey with Fresh Cream','price': 120},
{'name': 'Toffeed Banana', 'price': 110}],
'name': 'Sweet',
'description': 'Sweet and yummy'},
{'menu': [{'name': 'Mushroom Cheese Gratin','price': 175},
{'name': 'Pepper Chicken Waffle', 'price': 180}],
'name': 'Savoury',
'description' : 'Salty and yummy'}]
}
menu = []
for category in d.get('subCategories', []):
category['name'] = "{}({})".format(d['name'], category.get('name', ''))
menu.append(category)
pprint.pprint(menu)
and the sample output
[{'description': 'Sweet and yummy',
'menu': [{'name': 'Fig & Honey with Fresh Cream', 'price': 120},
{'name': 'Toffeed Banana', 'price': 110}],
'name': 'Waffles(Sweet)'},
{'description': 'Salty and yummy',
'menu': [{'name': 'Mushroom Cheese Gratin', 'price': 175},
{'name': 'Pepper Chicken Waffle', 'price': 180}],
'name': 'Waffles(Savoury)'}]

Answer 2

This is the code to do what you ask. Note that it can be optimized, but was left as is for readability.
dict = #your dictionary
# list to hold your new dictionaries (if there are more than one)
dict_list = []
# loop to extract
for item in dict['subCategories']:
d = {}
id = item['name']
# this could be made more compact
d.update({'name':'Waffles('+id+')'})
d.update({'menu':item['menu']})
d.update({'description':item['description']})
dict_list.append(d)
# print new dictionaries
for i in dict_list:
print(i)
Note that the program could be made more robust to handle arbitrary yamls (or json, I don't know what format this dictionary came from) if needed. Here the keys for extraction are hard coded.
Best of luck!
ps: there was formatting error in your starting dictionary
