【Python】對我本身的博客進行統計，看看哪年哪月發帖量最大

代碼很簡單，主要利用了requests進行網絡訪問，beautifulSoup進行頁面文本分析，re進行正則表達式抽取文字，前面兩個須要pip install name去安裝，後者是內部對象因此不用安裝。代碼以下，只有區區二十七行：

from bs4 import BeautifulSoup
import requests
import re

user_agent='Mozilla/4.0 (compatible;MEIE 5.5;windows NT)'
headers={'User-Agent':user_agent}

dic={}; #定義個字典對象，存月份和個數
for i in range(1,90):
    html=requests.get('http://www.cnblogs.com/xiandedanteng/p/?page='+str(i),headers=headers)
    soup= BeautifulSoup(html.text,'html.parser',from_encoding='utf-8');

    for descDiv in soup.find_all(class_="postDesc2"):
         rawInfo=descDiv.text #獲得class="postDesc2"的div的內容
         yearMonth=re.search(r'\d{4}-\d{2}',rawInfo).group() #用正則表達式去匹配年月並取其值

         # 將年月存入字典，若是存在就在原基礎上加一         
         if yearMonth in dic:
               dic[yearMonth]=dic[yearMonth]+1
         else:
               dic[yearMonth]=1


list=sorted(dic.items(),key=lambda x:x[1]) #將排序後的字典轉化爲數組
list.reverse()
for item in list:
    print(item)

而獲得的結果以下：

('2017-09', 80) 
('2019-10', 66) 
('2018-04', 56)

偶爾玩玩Python還挺有意思，這門技能可不能忘了。
