如何仅显示字典的某些部分？

Question

I have a dictionary with multiple keys but I only need to print part of it, i don't know how to do it though.

The output i have for my dictionary is:

[{'vin': '4T1R11AK7NU637019', 'askPrice': 28106.0, 'msrp': 28106.0, 'mileage': 0.0, 'isNew': True,
 'firstSeen': '2021-11-28', 'lastSeen': '2021-11-28', 'modelName': 'CAMRY', 'brandName': 'TOYOTA', 'year': 2022.0,
 'dealerID': 30873, 'color': 'Celestial Silver Metallic', 'interiorColor': 'Black', 'vinDecode': {(A LOT OF THINGS IN HERE}}},

 {'vin': '4T1G31AK7NU45B292', 'askPrice': 0.0, 'msrp': 0.0, 'mileage': 0.0, 'isNew': True,
  'firstSeen': '2021-11-28', 'lastSeen': '2021-11-28', 'modelName': 'CAMRY', 'brandName': 'TOYOTA', 'year': 2022.0,
  'dealerID': 12750, 'color': 'N/A', 'interiorColor': 'N/A', 'vinDecode': {(A LOT OF THINGS IN HERE}}}]

So there are multiple vin s and i would just like to print from vin to interiorColor for every entry; completely ignoring the vinDecode part. Is there any way I could do it?

Answer 1

Loop over the items in the dict. Skip the 'vinDecode' key.

for key, value in mydict.items():
    if key != 'vinDecode':
        print(f'{key}={value}')

Answer 2

You can't do that and you shouldn't anyway because if you can't control the source of this data new keys might appear in the future.

It is best to create a list of keys you are interested in and only print those:

my_list_of_dicts = [
    {'vin': '4T1R11AK7NU637019', 'askPrice': 28106.0, 'msrp': 28106.0, 'mileage': 0.0, 'isNew': True,
     'firstSeen': '2021-11-28', 'lastSeen': '2021-11-28', 'modelName': 'CAMRY', 'brandName': 'TOYOTA', 'year': 2022.0,
     'dealerID': 30873, 'color': 'Celestial Silver Metallic', 'interiorColor': 'Black', 'vinDecode': []},
     {'vin': '4T1G31AK7NU45B292', 'askPrice': 0.0, 'msrp': 0.0, 'mileage': 0.0, 'isNew': True,
      'firstSeen': '2021-11-28', 'lastSeen': '2021-11-28', 'modelName': 'CAMRY', 'brandName': 'TOYOTA', 'year': 2022.0,
      'dealerID': 12750, 'color': 'N/A', 'interiorColor': 'N/A', 'vinDecode': []}]

keys_i_am_interested_in = {'vin', 'askPrice', 'interiorColor'}

for d in my_list_of_dicts:
    print({k: v for k, v in d.items() if k in keys_i_am_interested_in})

this will print

{'vin': '4T1R11AK7NU637019', 'askPrice': 28106.0, 'interiorColor': 'Black'}
{'vin': '4T1G31AK7NU45B292', 'askPrice': 0.0, 'interiorColor': 'N/A'}

Answer 3

You can use .pop() on the dictionary to remove data:

for item in items:
    item.pop("vinDecode")
    print(item)

Answer 4

You can also create modified list containing dictionaries with vindecode removed. Later, you can print it.

vin_dict = [{'vin': '4T1R11AK7NU637019', 'askPrice': 28106.0, 'msrp': 28106.0, 'mileage': 0.0, 'isNew': True, 'firstSeen': '2021-11-28', 'lastSeen': '2021-11-28', 'modelName': 'CAMRY', 'brandName': 'TOYOTA', 'year':
2022.0, 'dealerID': 30873, 'color': 'Celestial Silver Metallic', 'interiorColor': 'Black', 'vinDecode': ''}, {'vin': '4T1G31AK7NU45B292', 'askPrice': 0.0, 'msrp': 0.0, 'mileage':
0.0, 'isNew': True, 'firstSeen': '2021-11-28', 'lastSeen': '2021-11-28', 'modelName': 'CAMRY', 'brandName': 'TOYOTA', 'year':
2022.0, 'dealerID': 12750, 'color': 'N/A', 'interiorColor': 'N/A', 'vinDecode': ''}]


# Remove specific Key from Dictionary List
modified_vin_dict = [{key : val for key, val in vin.items() if key != 'vinDecode'} for vin in vin_dict]

for d in modified_vin_dict:
    for k, v in d.items():
        print(f'{k}:{v}')
