取得校園新聞的編號
?
>>> url1 = 'http://news.gzcc.cn/html/2017/xiaoyuanxinwen_1027/8443.html'
>>> url1[-14:-5]
https://docs.python.org/3/library/turtle.html
產生python文檔的網址
?
>>> addr1 = 'https://docs.python.org/3/library/'
>>> addr2 = '.html'
>>> print(addr1 + 'turtle' + addr2)
http://news.gzcc.cn/html/xiaoyuanxinwen/4.html
產生校園新聞的一系列新聞頁網址
?
>>> addr1 = 'http://news.gzcc.cn/html/xiaoyuanxinwen/'
>>> addr2 = '.html'
>>> for i in range(2,10):print(addr1 + str(i) + addr2)
練習字符串內建函數：strip,lstrip,rstrip,split,count，replace
用函數得到校園新聞編號
>>> url = 'http://news.gzcc.cn/html/2017/xiaoyuanxinwen_1027/8443.html'
>>> print(url.rstrip('.html').split('_')[1])用函數統計一歌詞(文章、小說)中單詞出現的次數，替換標點符號為空格，用空格進行分詞。

人們都說：“桂林山水甲天下。”我們乘著木船，蕩漾在漓江上，來觀賞桂林的山水。我看見過波瀾壯闊的大海，玩賞過水平如鏡的西湖，卻從沒看見過漓江這樣的水。漓江的水真靜啊，靜得讓你感覺不到它在流動；漓江的水真清啊，清得可以看見江底的沙石；漓江的水真綠啊，綠得仿佛那是一塊無瑕的翡翠。船槳激起的微波擴散出一道道水紋，才讓你感覺到船在前進，岸在后移。我攀登過峰巒雄偉的泰山，游覽過紅葉似火的香山，卻從沒看見過桂林這一帶的山，桂林的山真奇啊，一座座拔地而起，各不相連，像老人，像巨象，像駱駝，奇峰羅列，形態萬千；桂林的山真秀啊，像翠綠的屏障，像新生的竹筍，色彩明麗，倒映水中；桂林的山真險啊，危峰兀立，怪石嶙峋，好像一不小心就會栽倒下來。這樣的山圍繞著這樣的水，這樣的水倒映著這樣的山，再加上空中云霧迷蒙，山間綠樹紅花，江上竹筏小舟，讓你感到像是走進了連綿不斷的畫卷，真是“舟行碧波上，人在畫中游”。'''
