I have several dictionaries in a list with this structure:
[{'store': 'walmart',
'store_id': 0,
'store_info': {'grapes': {'availability': {'No': 1, 'Yes': 1}},
'tomatoes': {'availability': {'No': 5, 'Yes': 6}},
'oranges': {'availability': {'No': 2, 'Yes': 2}},
'bottled water': {'availability': {'No': 10, 'Yes': 5}},
"india's mangos": {'availability': {'No': 3, 'Yes': 5}},
'water melon': {'availability': {'No': 2, 'Yes': 2}},
'lemons': {'availability': {'No': 2, 'Yes': 3}},
'kiwifruit': {'availability': {'No': 4, 'Yes': 2}},
'pineapple': {'availability': {'No': 5, 'Yes': 20}},
'total_yes': 23,
'total_no': 23,
'total': 46,
'id': [3, 4, 6, 2, 1, 6, 1, 4, 2]}},
{'store': 'Costco',
'store_id': 24,
'store_info': {'papaya': {'availability': {'No': 1, 'Yes': 1}},
'lychee': {'availability': {'No': 5, 'Yes': 1}},
'fig': {'availability': {'No': 2, 'Yes': 2}},
'blackberry': {'availability': {'No': 2, 'Yes': 5}},
"india's mangos": {'availability': {'No': 3, 'Yes': 5}},
'plum': {'availability': {'No': 1, 'Yes': 2}},
'total_yes': 43,
'total_no': 3,
'total': 46,
'id': [3, 4, 36, 2, 1, 1, 2, 4, 2]}}
]
How can I filter all the Yes and No values which are greater or equal to 5 at the same time? For example, given the above dict. The expected output should look like this if the dictionary fullfil the condition:
[
{'store': 'walmart',
'store_id': 0,
'store_info': {
'tomatoes': {'availability': {'No': 5, 'Yes': 6}},
'bottled water': {'availability': {'No': 10, 'Yes': 5}},
'pineapple': {'availability': {'No': 5, 'Yes': 20}},
'total_yes': 23,
'total_no': 23,
'total': 46,
'id': [3, 4, 6, 2, 1, 6, 1, 4, 2]}
}
]
In the above example, 'india's mangos': {'availability': {'No': 3, 'Yes': 5}}
should be filtered or removed. Because, although the 5 fullfil Yes treshold, the key No, doesnt fulfill the treshold at the same time. Alternatively, 'pineapple': {'availability': {'No': 5, 'Yes': 20}}
, should remain in the dict, because Yes
key has as values 20, which is greater than the 5 threshold. Finally, the second dict (costco) should be removed because none of its keys are at leas 5.
So far I tried to iterate over the structure, however, I am making too many loops, is there a more compact way of getting the expected output?:
a_lis = []
for e in list_dict:
try:
l = list(e['store_info'].keys())
for i in l:
#print(e['store_info'][i]['availability'])
if e['store_info'][i]['availability']['No']>=5 and e['availability'][i]['availability']['Yes']>= 5:
a_lis.append(e['store_info'][i]['availability'])
print(a_lis)
else:
pass
except TypeError:
pass
That's not difficult.I would recommend you create a new list.(And revise the dictionary directly.)
lst = [{'store': 'walmart',
'store_id': 0,
'store_info': {'grapes': {'availability': {'No': 1, 'Yes': 1}},
'tomatoes': {'availability': {'No': 5, 'Yes': 6}},
'oranges': {'availability': {'No': 2, 'Yes': 2}},
'bottled water': {'availability': {'No': 10, 'Yes': 5}},
'india\'s mangos': {'availability': {'No': 3, 'Yes': 5}},
'water melon': {'availability': {'No': 2, 'Yes': 2}},
'lemons': {'availability': {'No': 2, 'Yes': 3}},
'kiwifruit': {'availability': {'No': 4, 'Yes': 2}},
'pineapple': {'availability': {'No': 5, 'Yes': 20}},
'total_yes': 23,
'total_no': 23,
'total': 46,
'id': [3, 4, 6, 2, 1, 6, 1, 4, 2]}},
{'store': 'Costco',
'store_id': 24,
'store_info': {
'papaya': {'availability': {'No': 1, 'Yes': 1}},
'lychee': {'availability': {'No': 5, 'Yes': 1}},
'fig': {'availability': {'No': 2, 'Yes': 2}},
'blackberry': {'availability': {'No': 2, 'Yes': 5}},
'india\'s mangos': {'availability': {'No': 3, 'Yes': 5}},
'plum': {'availability': {'No': 1, 'Yes': 2}},
'total_yes': 43,
'total_no': 3,
'total': 46,
'id': [3, 4, 36, 2, 1, 1, 2, 4, 2]}}
]
result_list = []
for sub_dict in lst:
if sub_dict['store_info']['total_yes'] >= 5 and sub_dict['store_info']['total_no'] >= 5:
result_list.append(sub_dict)
key_need_to_be_removed = [k for k, v in sub_dict['store_info'].items() if type(v) is dict and (v['availability']['Yes'] < 5 or v['availability']['No'] < 5)]
for k in key_need_to_be_removed: # remove the dict under dictionary['store_info']
del sub_dict['store_info'][k]
print(result_list)
Result:
[{
'store': 'walmart',
'store_id': 0,
'store_info': {
'tomatoes': {
'availability': {
'No': 5,
'Yes': 6
}
},
'bottled water': {
'availability': {
'No': 10,
'Yes': 5
}
},
'pineapple': {
'availability': {
'No': 5,
'Yes': 20
}
},
'total_yes': 23,
'total_no': 23,
'total': 46,
'id': [3, 4, 6, 2, 1, 6, 1, 4, 2]
}
}]
Here is another approach:
# where data is the input
filtered = []
for store in data:
avail_dict = {}
extra_dict = {}
for item, value in store['store_info'].items():
if isinstance(value, dict):
okay = value['availability'].get('No',0) >= 5 and value['availability'].get('Yes',0) >= 5
if okay:
avail_dict[item] = value
else:
extra_dict[item] = value
if avail_dict:
avail_dict.update(extra_dict)
new_store = dict(store)
new_store['store_info'] = avail_dict
filtered.append(new_store)
Result for filtered
(input data
is unchanged):
[{'store': 'walmart',
'store_id': 0,
'store_info': {'tomatoes': {'availability': {'No': 5, 'Yes': 6}},
'bottled water': {'availability': {'No': 10, 'Yes': 5}},
'pineapple': {'availability': {'No': 5, 'Yes': 20}},
'total_yes': 23,
'total_no': 23,
'total': 46,
'id': [3, 4, 6, 2, 1, 6, 1, 4, 2]}}]
