Python3 simple web directory scan script (complete update later)

I need to traverse the directory in the process of doing the problem, I simply wrote the scan script, but I have not learned multi-threading, so let ’s do it first.

import urllib.request as req
import urllib.error as er,sys
file_hou=['.tar','.tat.gz','.zip','.rar','.bak']
file_name=['web','website','backup','back','www','wwwroot','temp']
f=open("D:/lenovo/desktop/ctfhub.txt",'a',encoding=('utf-8'))
web_success=[]
n=(len(file_name)*len(file_hou))
nn=0
for x in file_name:
    for y in file_hou:
        try:
            url = 'http://taobao.com'+x+y
            webpage = req.urlopen(url)  # 根据超链访问链接的网页
            #print(url + "  ok")
            web_success.append(url)
        except er.HTTPError as e:
            #print(url + "  ", e)#显示错误信息
            pass
        except er.URLError as f:
            #print(url + "  ", f)#显示错误信息
            pass
        except:
            #print(sys.exc_info())#显示错误信息
            raise
        nn+=1
        print("%.2f"%((nn/n)*100),"%")#进度显示
for x in web_success:
    f.write(x)

note:

• The HTTPError and URLError exception handling in urllib2 have been merged into urllib
• If you want to save the result to the text, open the text with encoding = ('utf-8'), txt defaults to gbk encoding, and pycharm also uses the system encoding by default.
