从嵌套列表的深层提取命名元素的通用方法

def extract_element(nested_list, target_name):
    result = []
    for item in nested_list:
        if isinstance(item, list):
            result.extend(extract_element(item, target_name))
        elif isinstance(item, dict):
            if target_name in item:
                result.append(item[target_name])
        else:
            continue
    return result

nested_list = [
    "a",
    ["b", "c", {"name": "d"}],
    ["e", {"name": "f"}],
    "g"
]

target_name = "name"

result = extract_element(nested_list, target_name)
print(result)

['d', 'f']
