python判断给定的日期是周几（2种方法） 、获取某一年每月的日历数据、获取法定节假日接口

1、判断给定的日期是周几（2种方法）：

方法一：

from datetime import datetime
week = datetime.strptime("20191212","%Y%m%d").weekday()  # 直接获得周几数据
week = datetime.now().weekday()

方法二：

import calendar
calendar.weekday(2019,12,12) + 1  # 下标从0开始，算周几时需要加1

2、获取某一年每月的日历数据：

calendar_add_list = []
for month in range(1, 13):  # 遍历1-12月
    week_list = calendar.monthcalendar(year, month)  # 按周的格式，获取每月日历

3、获取法定节假日接口 

以国务院发布的公告为准，随时调整及增加；http://www.gov.cn/zfwj/bgtfd.htm或http://www.gov.cn/zhengce/xxgkzl.htm 

 

4、获取官方节假日数据：

import calendar
from  urllib import request
from random import randrange
import json
import time

year = 2020
data_list = []
for month in range(1,13):
    week_list = calendar.monthcalendar(year,month)
    for i in week_list:
        for j in i:
            if j!=0:
                # 法定节假日信息
                current_date = "%s%02d%02d" % (year, month, j)
                # target_url = "http://www.easybots.cn/api/holiday.php?d=" + current_date
                # target_url = "http://api.goseek.cn/Tools/holiday?date=" + current_date
                target_url = "http://tool.bitefu.net/jiari/?back=json&d=" + current_date
                print(target_url)
                headers = [
                    ("Accept","text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3"),
                    ("Accept-Encoding", "gzip, deflate"),

                    ("Connection", "keep-alive"),
                    ("Host", "api.goseek.cn"),
                    ("Upgrade-Insecure-Requests", 1),
                    ("User-Agent", "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.108 Safari/537.36")
                ]

                opener = request.build_opener()
                opener.addheaders = headers
                while 1:
                    try:
                        resp = opener.open(target_url).read()
                        # resp = request.urlopen(url=target_url).read()
                        if resp:
                            break
                    except Exception as err:
                        print("----")
                        pass

                print(resp)
                data = json.loads(resp)
                res = dict()
                res["data"] = data[current_date]
                res["date"] = current_date
                print(res)
                # resp = str(resp)[2:-1].replace("\"","'")
                data_list.append(res)
                time.sleep(randrange(1,5))

data = json.dumps(data_list)
with open("{}cla.json".format(year),"w",encoding="utf-8") as fp:
    fp.write(data)


with open("{}cla.json".format(year),"r",encoding="utf-8") as fp:
    a = fp.read()
    b = json.loads(a)
    print(a)

for i in b:
    print(i)
