我在下面写了这个函数，您可以将当前键名的名称更改为新名称。

def change_dictionary_key_name(dict_object, old_name, new_name):
    '''
    [PARAMETERS]: 
        dict_object (dict): The object of the dictionary to perform the change
        old_name (string): The original name of the key to be changed
        new_name (string): The new name of the key
    [RETURNS]:
        final_obj: The dictionary with the updated key names
    Take the dictionary and convert its keys to a list.
    Update the list with the new value and then convert the list of the new keys to 
    a new dictionary
    '''
    keys_list = list(dict_object.keys())
    for i in range(len(keys_list)):
        if (keys_list[i] == old_name):
            keys_list[i] = new_name

    final_obj = dict(zip(keys_list, list(dict_object.values()))) 
    return final_obj

假设一个JSON，你可以调用它，并通过以下行重命名它:

data = json.load(json_file)
for item in data:
    item = change_dictionary_key_name(item, old_key_name, new_key_name)

在这里可以找到从列表到字典键的转换:https://www.geeksforgeeks.org/python-ways-to-change-keys-in-dictionary/

如果你有一个复杂的字典，这意味着字典中有一个字典或列表:

myDict = {1:"one",2:{3:"three",4:"four"}}
myDict[2][5] = myDict[2].pop(4)
print myDict

Output
{1: 'one', 2: {3: 'three', 5: 'four'}}

注意pop的位置: 将你想要删除的键放在pop()之后 orig_dict['AAAAA'] = orig_dict.pop('A')

orig_dict = {'A': 1, 'B' : 5,  'C' : 10, 'D' : 15}   
# printing initial 
print ("original: ", orig_dict) 

# changing keys of dictionary 
orig_dict['AAAAA'] = orig_dict.pop('A')
  
# printing final result 
print ("Changed: ", str(orig_dict)) 

只需2步即可轻松完成:

dictionary[new_key] = dictionary[old_key]
del dictionary[old_key]

或者一步:

dictionary[new_key] = dictionary.pop(old_key)

如果字典[old_key]未定义，将引发KeyError。注意，这将删除字典[old_key]。

>>> dictionary = { 1: 'one', 2:'two', 3:'three' }
>>> dictionary['ONE'] = dictionary.pop(1)
>>> dictionary
{2: 'two', 3: 'three', 'ONE': 'one'}
>>> dictionary['ONE'] = dictionary.pop(1)
Traceback (most recent call last):
  File "<input>", line 1, in <module>
KeyError: 1

在python 2.7及更高版本中，您可以使用字典理解: 这是我在使用DictReader读取CSV时遇到的一个例子。用户已经在所有列名后面加上了':'

ori_dict ={“key1:”:1、“key2:”:2,“key3:”:3}

在键中去掉后面的':':

Corrected_dict = {k.replace(':'， "): v for k, v in ori_dict.items()}

我还没有看到确切的答案:

dict['key'] = value

您甚至可以对对象属性执行此操作。 通过这样做，将它们编入字典:

dict = vars(obj)

然后你可以像操作字典一样操作对象属性:

dict['attribute'] = value
