python函数的参数赋值问题

Question

python如何批量赋值?
我有这么个需求,一个python函数中有若干参数(**kwargs),这些参数需要用户输入,不输入的参数直接读取配置.

我怎么能一次取出没有给值的参数?好用这些参数去读取配置呢

from configparser import ConfigParser

        self.config = ConfigParser()
    
    """ kwdv.ini文件内容
    [info1]
    address=china
    gender=man
    count=3334
    """
    def init_info(self, name=None, age=None, phone=None, **kwargs):
        # name、age、phone三个参数是否需要合并给kwargs
        self.name = name
        self.age = age
        self.phone = phone
        # 加载某些参数的默认值
        self.config.read('comm/kwdv.ini', encoding="utf-8")
        info = self.config.items('info1')
        infoDict = dict(info)
        infoDict.update(kwargs)
        self.address = infoDict.get("address")
        self.gender = infoDict.get("gender")
        self.count = infoDict.get("count")

    def __str__(self) :
        return "KWargsDefValue[name={}, age={}, phone={}, address={}, gender={}, count={}]".format(self.name, self.age, self.phone, self.address, self.gender, self.count)

kwdv = KWargsDefValue()
kwdv.init_info(age = 33, count=900)
print(kwdv) # KWargsDefValue[name=None, age=33, age=None, phone=None, address=china, gender=man, count=900]
