Python - 嵌套字典删除键并更新字典名称

Question

I have a nested dictionary which contains a list and would like to do the following:

1. Update the dictionary name to A , B , C , D instead of dict1 , dict2
2. Remove key3 and it's values from the dictionary

Here is the current input example:

{'dict_1': {'key1': ['data1', 'data2', 'data3'], 'key2': ['1', '2', '3'], 'key3': ['value1', 'value2', 'value3']} 'dict_2': {'key1': ['data1', 'data2', 'data3'], 'key2': ['1', '2', '3'], 'key3': ['value1', 'value2', 'value3']}}

Desired output:

{'A': {'key1': ['data1', 'data2', 'data3'], 'key2': ['1', '2', '3']} 'B': {'key1': ['data1', 'data2', 'data3'], 'key2': ['1', '2', '3']}}

I have tried using ascii lowercase to change letter but this did not work. To remove key3 I tried using del and pop which did not work either. Please could someone let me know where I am going wrong?

Answer 1

Here is the solution involving ascii values and .pop() .

Try this :

nested_dict = {
    'dict_1': {'key1': ['data1', 'data2', 'data3'], 'key2': ['1', '2', '3'], 'key3': ['value1', 'value2', 'value3']},
    'dict_2': {'key1': ['data1', 'data2', 'data3'], 'key2': ['1', '2', '3'], 'key3': ['value1', 'value2', 'value3']}}

key_name = 'A'

new_nested_dict = {}

for k, v in nested_dict.items():
    v.pop('key3', None)
    new_nested_dict[key_name] = v
    key_name = chr(ord(key_name) + 1)

print(new_nested_dict)

Output:

{'A': {'key1': ['data1', 'data2', 'data3'], 'key2': ['1', '2', '3']}, 'B': {'key1': ['data1', 'data2', 'data3'], 'key2': ['1', '2', '3']}}
