根据两个日期时间之间的事件减少列表

我有一个对象列表,除了其他数据位之外,还包含一个日期,我需要创建一个列表,列出上个月任何时间该日期的所有对象,即上个月1日的午夜<目标数据<这个月1号午夜。

我还需要满足此条件的总对象数。

现在,我正在进行一系列while循环,但我觉得必须有更好的方法,特别是因为我的脚本挂起了:

        post = 0 #the current post we're analyzing
        posts = 0 #the total number of posts in the month we actually care about
        lastmonthposts = [] #I think i can just get rid of this
        blog = pyblog.WordPress()

        date = blog.get_recent_posts(1 + posts)[0]['dateCreated']
        while (date > startthismonth):
            print "So far, there have been " + str(posts) + " posts this month we've counted."
            post = post + 1
            date = blog.get_recent_posts(1 + post)[0]['dateCreated']
        while (date > startlastmonth):
            print "So far, there have been " + str(posts) + " posts last month we've counted, which is " + str(date.timetuple().tm_mon) + "."
            posts = posts + 1
            post = post + 1
            date = blog.get_recent_posts(1 + post)[0]['dateCreated']
            lastmonthposts.append('blog')
        for blogpost in lastmonthposts:
            postnumber = blogpost['postid']
            comments = comments + int(blog.get_comment_count(postnumber)['approved'])

答案 0 :(得分:2)

而不是get_recent_posts()我会使用get_page_list()

from datetime import datetime, timedelta

this_month_start = datetime.now().date().replace(day=1)
prev_month_start = (this_month_start - timedelta(days=1)).replace(day=1)

pages = blog.get_page_list()
last_month_pages = [
  p for p in pages
  if prev_month_start <= p['dateCreated'] < this_month_start]
last_month_approved_comment_count = sum(
  blog.get_comment_count(page['page_id'])['approved']
  for page in last_month_pages)

print "number of last month's pages:", len(last_month_pages)
print "number of approved comments for last month's pages:",
print last_month_approved_comment_count
