【Python】+字符串转换为日期（互转）

import datetime


class TestDate:
    def test_date(self):
        y, m, d = self.split("-")
        print("{}年{}月{}日".format(y, m, d))
        date = datetime.date(int(y), int(m), int(d))
        print(date)
        date = date + datetime.timedelta(days=-1)
        print(date)
        return date


if __name__ == "__main__":
    td = TestDate
    td.test_date("2019-10-24")
