在Python中运行多个查找和替换（在文件夹和子文件夹中的每个文件上）

Question

I have a folder (courses) with sub-folders and a random number of files. I want to run multiple search and replaces on those random files. Is it possible to do a wild card search for .html and have the replaces run on every html file ?

Search and replaces:

1) "</b>" to "</strong>"

2) "</a>" to "</h>"

3) "<p>" to "</p>"

Also all these replaces have to be run on every file in the folder and sub-folders.

Thank you so much

Answer 1

Try this,

import os
from os.path import walk

mydict = {"</b>":"</strong>", "</a>":"</h>", "<p>":"</p>"}

for (path, dirs, files) in os.walk('./'):
    for f in files:
        if f.endswith('.html'):
            filepath = os.path.join(path,f)
            s = open(filepath).read()
            for k, v in mydict.iteritems():
                s = s.replace(k, v)
            f = open(filepath, 'w')
            f.write(s)
            f.close()

You can change os.walk('./') to os.walk('/anyFolder/')

使用glob模块获取*.html文件列表。
