datetime 模塊,獲取當前星期幾

#! /usr/bin/env python
# -*- coding:utf-8 -*-

import datetime


def get_week_day(date):
    week_day = {
        0: '星期一',
        1: '星期二',
        2: '星期三',
        3: '星期四',
        4: '星期五',
        5: '星期六',
        6: '星期日',
    }
    day = date.weekday()  # weekday()能夠得到是星期幾
    return week_day[day]


print(datetime.date.today(), get_week_day(datetime.date.today()))固然 datetime 模塊下還有 isoweekday() 方法, 可是原理大同小異,  isoweekday() 方法直接返回的是1-7
