如何在嵌套字典中分发列表的值？

def distribute_list_values(dictionary):
    for key, value in dictionary.items():
        if isinstance(value, list):
            distribute_list_values_in_dict(value)
        elif isinstance(value, dict):
            distribute_list_values(value)

def distribute_list_values_in_dict(dictionary):
    for key, value in dictionary.items():
        if isinstance(value, list):
            for i, item in enumerate(value):
                dictionary[key + str(i)] = item
            del dictionary[key]

# 示例嵌套字典
nested_dict = {
    'key1': 'value1',
    'key2': ['value2', 'value3'],
    'key3': {
        'subkey1': 'subvalue1',
        'subkey2': ['subvalue2', 'subvalue3']
    }
}

distribute_list_values(nested_dict)
print(nested_dict)

{
    'key1': 'value1',
    'key2': 'value2',
    'key20': 'value3',
    'key3': {
        'subkey1': 'subvalue1',
        'subkey2': 'subvalue2',
        'subkey21': 'subvalue3'
    }
}
