不足:python

  一、獲取網頁的代碼能夠重複利用,這裏沒有寫好!懶,主要是。編程

  二、仍是沒有用面向對象編程(白天試了,有些地方不懂,就pass了)app

  三、沒有按本身的要求保存數據。url

  四、可能會抓取到重複,由於用的是列表,沒有用集合。spa

  五、抓取的網頁信息是從最後一項開始抓取的,這樣也很差。code

 

我怎麼感受寫的不足愈來愈多了啊 ,加了好幾條了,(⊙﹏⊙)b,算了不寫了,就這樣吧,在寫下去都沒有信心了!xml

 

不過整體來講仍是完成了本身想要實現的目的,抓取每一個工做的網址,並根據抓取的網址老獲取想要的信息!對象

有點進步,最起碼代碼就長了點了。blog
