从 python 中的字典列表中删除重复的字典

Question

I want to remove duplicates dictionaries from list of dictionaries. I am trying to make configurable code to work on any field instead of making field specific.

Input Data

dct = {'Customer_Number': 90617174, 
       'Phone_Number': [{'Phone_Type': 'Mobile', 'Phone': [12177218280.0]}, 
                        {'Phone_Type': 'Mobile', 'Phone': [12177218280.0]}],
       'Email': [{'Email_Type': 'Primary', 
                  'Email': ['saman.zonouz@rutgers.edu']},
                 {'Email_Type': 'Primary', 
                  'Email': ['saman.zonouz@rutgers.edu']}]
      }

Output Data:

deduped_dict = {'Customer_Number': 90617174, 
                'Email': [{'Email_Type': 'Primary', 
                           'Email': ['saman.zonouz@rutgers.edu']}], 
                'Phone_Number': [{'Phone_Type': 'Mobile', 
                                  'Phone': [12177218280]}]}

**Code tried:**

    res_list = []
    for i in range(len(dic)):
        if dic[i] not in dic[i + 1:]:
            res_list.append(dic[i])

Answer 1

Write a function to dedupe lists:

def dedupe_list(lst):
    result = []
    for el in lst:
        if el not in result:
            result.append(el)
    return result

def dedupe_dict_values(dct):
    result = {}
    for key in dct:
        if type(dct[key]) is list:
            result[key] = dedupe_list(dct[key])
        else:
            result[key] = dct[key]
    return result

# Test it:
dedupe_dict_values(dct) == deduped_dict
## Out[12]: True
