python处理url
我现在有一些这样的数据，用来生成url，以提供给爬虫进行爬取。
Venture Capital
Banking (excl. Investment Banking)
Washington, D.C.
Nightlife in Washington, DC
Amazon $175mm Investment in LivingSocial (December 2010)
Twitter's Future
Florian Leibert / Noirin Shirley Incident
这些数据最终要以 - 进行连接，来生成地址。
上代码:
#ipython 下执行
import re
In [41]: path = re.sub("[?@ =#().&]", "-", "Banking (excl. Investment Banking)")
In [42]: path
Out[42]: 'Banking--excl--Investment-Banking-'
In [43]: path1 = re.sub("-+","-",path)
In [44]: path1
Out[44]: 'Banking-excl-Investment-Banking-'
In [45]: path1.rstrip('-')
Out[45]: 'Banking-excl-Investment-Banking'
如果有一些新发现的奇怪字符，在
re.sub("[?@ =#().&]", "-", "Banking (excl. Investment Banking)")
那一堆符号里面加上新符号就是了。
