如何遍历嵌套对象以检查是否找到true？

def check_true(obj):
    if isinstance(obj, dict):
        for key, value in obj.items():
            if value == True:
                return True
            elif isinstance(value, (dict, list)):
                if check_true(value):
                    return True
    elif isinstance(obj, list):
        for item in obj:
            if item == True:
                return True
            elif isinstance(item, (dict, list)):
                if check_true(item):
                    return True
    return False
