补充:python 黑名单过滤
需要过滤一些词语
写了下面这个函数,在blacklist 文件中添加需要过滤的词语
1
2

#过滤黑名单列表中出现的
def in_lists( str ):
str_lists = []
fd = open ( './filter/blacklist' )
for line in fd.readlines():
str_lists.append(line.strip())
if str in str_lists:
return 0
else :
return 1
|
通过 python 自带的 filter函数 调用, in_lists ,filter函数会过滤掉 bool 值为 1 的列表中的元素
filter( in_lists , urls )
总结
以上所述是小编给大家介绍的python下载文件记录黑名单,希望对大家有所帮助,如果大家有任何疑问请给我留言,小编会及时回复大家的。在此也非常感谢大家对服务器之家网站的支持!
