如何将由mongo ObjectIds列表构建的字符串转换为只包含ids的python列表

from bson import ObjectId

def convert_string_to_ids(string):
    ids = []
    # 将字符串按逗号分割成单个ObjectId字符串
    id_strings = string.split(',')
    for id_string in id_strings:
        # 将每个ObjectId字符串转换为ObjectId类型，并提取其中的id
        id = str(ObjectId(id_string.strip()))
        ids.append(id)
    return ids

mongo_ids_string = "ObjectId('60c7a5e7e6a4a7a0a8e6c7b8'), ObjectId('60c7a5e7e6a4a7a0a8e6c7b9'), ObjectId('60c7a5e7e6a4a7a0a8e6c7ba')"
ids_list = convert_string_to_ids(mongo_ids_string)
print(ids_list)
