取得校园新闻的编号：

a = "http://news.gzcc.cn/html/2017/xiaoyuanxinwen_1027/8443.html"
a=a.rstrip(".html")
a=a[-9:]
print(a)

产生python文档的网址:

def strCat(html,x):
    b=html[:-11]
    c=html[-5:]
    d=b+x+c
    print(d)

    
strCat("https://docs.python.org/3/library/turtle.html","intro")

产生校园新闻的一系列新闻页网址:

a = "http://news.gzcc.cn/html/xiaoyuanxinwen/4.html"
b=a[:-6]
c=a[-5:]
for i in range(5):
    d=""
    d=b+str(i)+c
    print(d)
