python - 关于代码的优化问题

Question

我新手写的代码，用来处理爬虫下来的htm文件内容,虽然解决问题，但是会有遗漏文件不处理。爬虫是爬一些文章的网站下来的，和网页另存为没什么区别。

想大神们帮我看看我的代码，怎么优化不会有遗漏。比较小白的代码，麻烦了！！！

# -*- coding: utf-8 -*
import re
import glob

filename_list = glob.glob('*.html')

for i in filename_list:
    txt = ""
    with open(i, "r") as htmfile:
        txt = htmfile.read()
    scdy = r"<hr[\s\S]*?<hr"
    onedotxt = re.findall(scdy, txt)
    if onedotxt:
        r = onedotxt[0]
    twotxt=re.sub('<[^>]*>', '', r) 
    threetxt=re.sub('<hr', '', twotxt)
    fourtxt=re.sub('&#8217;', '', threetxt)
    fivetxt=re.sub('&#8221;', '"', fourtxt)
    sixtxt=re.sub('&#8220;', '"', fivetxt)
    
    endstr=re.sub('&#8211;', '-', sixtxt)
    name = endstr.split('\n')[1]
    with open(name+".txt", "w") as wf:
            wf.write(endstr)

filename_list = glob.glob('.html') + glob.glob('.htm')
