使用python爬虫 taobao 过多请求导致超时

[量化分析]

f=open(filename,'wb')
			user_agent='Mozilla/4.0 (compatible; MSIE 5.5; Windows NT)'
			header={'User-Agent':user_agent}
			req=urllib2.Request(i[0],headers=header)
			resp=urllib2.urlopen(req)
			data=resp.read()
			f.write(data)
			f.close()
			time.sleep(10)

Traceback (most recent call last):

经常返回以上错误，请问有什么办法可以避免？ 按道理已经设置了sleep 10 可以避开ddos了呀
是不是urllib也需要close函数才行？？？？
