Python+SeaTable实现计算两个日期间的工作日天数

import datetime
from enum import Enum
from seatable_api import dateutils, Base, context

# 一个 Base 的授权信息
SERVER_URL = context.server_url or 'https://cloud.seatable.cn'
API_TOKEN = context.api_token or 'dd46f9ca0172a850a0922107a6b2e6b99932b040'

# 1. 定义中国的节假日概况
class Holiday(Enum):
    new_years_day = "元旦"
    spring_festival = "春节"

    labour_day ="劳动节"
    dragon_boat_festival = "端午"
    national_day = "国庆节"
    mid_autumn_festival = "中秋"

# 2. 列出节假日列表， 此处可以去查询日历，就不一一列出了
holidays = {
    datetime.date(year=2022, month=1, day=1): Holiday.new_years_day.value,
    datetime.date(year=2022, month=1, day=2): Holiday.new_years_day.value,
    datetime.date(year=2022, month=1, day=3): Holiday.new_years_day.value,
    datetime.date(year=2022, month=1, day=31): Holiday.spring_festival.value,
    datetime.date(year=2022, month=2, day=1): Holiday.spring_festival.value,
    .....
}

# 3.列出调休日的列表，及周六日为工作日的列表
workdays = {
    datetime.date(year=2022, month=1, day=29): Holiday.spring_festival.value,
    datetime.date(year=2022, month=1, day=30): Holiday.spring_festival.value,

    datetime.date(year=2022, month=10, day=9): Holiday.national_day.value,
    ....
}

# 4. 定义是否是工作日
def is_workday(date):
    '''
    工作日定义：
    1. 日期在workdays字典的key中
    2. 星期是周一到周五且不在holidays字典的key中
    '''
    date = _validate_date(date)
    weekday = date.weekday()
    return bool(date in workdays.keys() or (weekday <= 4 and date not in holidays.keys()))
    
# 5. 计算两个日期之间的工作日， 此处返回的是工作日的列表， 该列表的长度即是工作日的天数
def get_workdays(start, end):
    """
    获取两个日期之间的工作日，返回datetime的列表
    """
