从键和子键中检索所有嵌套值，直到python字典中没有键为止

def retrieve_nested_values(dictionary):
    values = []
    for key, value in dictionary.items():
        if isinstance(value, dict):
            values.extend(retrieve_nested_values(value))
        else:
            values.append(value)
    return values

# 示例字典
example_dict = {
    'key1': 'value1',
    'key2': {
        'key3': 'value3',
        'key4': {
            'key5': 'value5',
            'key6': 'value6'
        }
    },
    'key7': 'value7'
}

result = retrieve_nested_values(example_dict)
print(result)

['value1', 'value3', 'value5', 'value6', 'value7']
