Question

我是python的新手使用Python 2.7我想要实现的是我在脚本中获得了url列表，每个url需要在cronjob中的特定日期运行。我需要import datetime和import time获取服务器日("%A")并与当天运行的网址匹配，这样可以为每个执行相同脚本的网址节省我的费用

import urllib2,urllib
import re,os
import datetime
import time

mylist={
monday:'http://www.trt.tv/baba-candir/bolumler/80212',
thusday:'http://www.trt.tv/filinta/bolumler/20198',
wensday:'http://www.trt.tv/dirilis-ertugrul/bolumler/20196',
}
for days in mylist:
    print days
    req = urllib2.Request(url)
    req.add_header('User-Agent', 'Mozilla/5.0 (Windows; U; Windows NT 5.1; az-AZ; rv:1.9.0.3) Gecko/2008092417 Firefox/3.0.3')
    response = urllib2.urlopen(req)
    link=response.read()
    response.close()

Answer 1

from datetime import date

today = date.today().strftime('%A')

例如，如果今天是星期一，那么这将在周一返回＆＃39;如果你想要它是小写的，你可以这样做：today.lower（）

所有在一起：

import urllib2,urllib
import re,os
import time
from datetime import date

mylist = {
    'Monday':'http://www.trt.tv/baba-candir/bolumler/80212',
    'Thursday':'http://www.trt.tv/filinta/bolumler/20198',
    'Wednesday':'http://www.trt.tv/dirilis-ertugrul/bolumler/20196',
}


today = date.today().strftime('%A')
if today in mylist:
    url = mylist[today]

    req = urllib2.Request(url)
    req.add_header('User-Agent', 'Mozilla/5.0 (Windows; U; Windows NT 5.1; az-AZ; rv:1.9.0.3) Gecko/2008092417 Firefox/3.0.3')
    response = urllib2.urlopen(req)
    link=response.read()
    response.close()

Answer 2

正如this answer所述，可以从

获取日期

import datetime
print(datetime.datetime.today().weekday())
# prints '0' because it's Monday

打印0（星期一）到6（星期日）之间的数字。所以，在你的代码中（如果我理解正确的话）：

import urllib2,urllib
import re,os
import datetime
import time

mylist={
0:'http://www.trt.tv/baba-candir/bolumler/80212',
1:'http://www.trt.tv/filinta/bolumler/20198',
2:'http://www.trt.tv/dirilis-ertugrul/bolumler/20196',
}

today = datetime.datetime.today().weekday()
if today in mylist:
    # Forgotten?
    url = mylist[today]
    # Forgotten?     

    req = urllib2.Request(url)
    req.add_header('User-Agent', 'Mozilla/5.0 (Windows; U; Windows NT 5.1; az-AZ; rv:1.9.0.3) Gecko/2008092417 Firefox/3.0.3')
    response = urllib2.urlopen(req)
    link=response.read()
    response.close()
else:
    print('error: today (day %s) was not found in mylist.' % today)

仅导入从URL列表指定的日期
