Python如何根据日期判断周几

1、方法一：#!/usr/bin/python# -*- coding:utf-8 -*-from datetime import datetimetoday = datetime.now().weekday() + 1print(today)week = datetime.strptime("20191018","%Y%m%d").weekday() + 1print(week)

2、方法二：#!/usr/bin/python# -*- coding:utf-8 -*-from datetime import datetimeapply_tim髫潋啜缅e = 20191018apply_time = datetime.utcfromtimestamp(apply_time)time_str = apply_time.strftime("%Y-%m-%d %H:%M:%S")apply_hour = time_str.split(" ")[1].split(":")[0]apply_week = datetime.strptime(time_str.split(" ")[0], "%Y-%m-%d").weekday()print(apply_week)

3、方法三：#!/usr/bin/python# -*- coding:utf-8 -*-import time, datetimedef get_week_day(date):week_day_dict = {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: '星期天',}day = date.weekday()return week_day_dict[day]print(get_week_day(datetime.datetime.now()))

4、判断昨天是作辈碇锅周几：#!/usr/bin/python# -*- coding:utf-8 -*-import tim髫潋啜缅e, datetimetoday = datetime.date.today()yesterday = today - datetime.timedelta(days=1)#获取昨天是星期几thistime=yesterday.isoweekday()if thistime==1:a="周一"elif thistime==2:a="周二"elif thistime==3:a="周三"elif thistime==4:a="周四"elif thistime==5:a="周五"elif thistime==6:a="周六"elif thistime==7:a="周日"print(a)
