Browse files and subfolders in Python

I'd like to browse through the current folder and all its subfolders and get all the files with .htm|.html extensions. I have found out that it is possible to find out whether an object is a dir or file like this:

import os

dirList = os.listdir("./") # current directory
for dir in dirList:
  if os.path.isdir(dir) == True:
    # I don't know how to get into this dir and do the same thing here
  else:
    # I got file and i can regexp if it is .htm|html

and in the end, I would like to have all the files and their paths in an array. Is something like that possible?

Solution 1:

You can use os.walk() to recursively iterate through a directory and all its subdirectories:

for root, dirs, files in os.walk(path):
    for name in files:
        if name.endswith((".html", ".htm")):
            # whatever

To build a list of these names, you can use a list comprehension:

htmlfiles = [os.path.join(root, name)
             for root, dirs, files in os.walk(path)
             for name in files
             if name.endswith((".html", ".htm"))]

Solution 2:

I had a similar thing to work on, and this is how I did it.

import os

rootdir = os.getcwd()

for subdir, dirs, files in os.walk(rootdir):
    for file in files:
        #print os.path.join(subdir, file)
        filepath = subdir + os.sep + file

        if filepath.endswith(".html"):
            print (filepath)

Hope this helps.
