如何按天获取参数值？

import datetime

def get_parameter_by_day():
    current_date = datetime.date.today()
    # 根据当前日期获取参数值的逻辑
    parameter_value = None
    if current_date == datetime.date(2022, 1, 1):
        parameter_value = "Value for January 1st"
    elif current_date == datetime.date(2022, 1, 2):
        parameter_value = "Value for January 2nd"
    # 其他日期的参数值逻辑...

    return parameter_value

# 调用函数获取当天的参数值
value = get_parameter_by_day()
print(value)
