Re: Walk thru each subdirectory from a top directory

[Jeff McNeil]

Isn't this something that os.walk would be good for?

import os
for t in os.walk(base_dir):
    for f in t[2]:
        print "/".join((t[0], f))

I had a do something similar. I had to get a program to traverse through a directory and delete all files with a specific file extension. (The program below will delete files, so I do not recommend you running it without paying close attention to it.)

This program will start at a given directory and will traverse thru the subdirectories by using "listdir".

i am trying to use python to walk thru each subdirectory from a top
directory.  Here is my script:

savedPagesDirectory = "/home/meryl/saved_pages/data"

dir=open(savedPagesDirectory, 'r')

for file in dir:
    if (isdir(file)):
        # get the full path of the file
        fileName = savedPagesDirectory + file + 'index.html'
        print fileName

$ ./scripts/regressionTest.py
Traceback (most recent call last):
  File "./scripts/regressionTest.py", line 12, in ?
    dir=open(savedPagesDirectory, 'r')
IOError: [Errno 21] Is a directory

But I get the above error:

Can you please tell me what did I do wrong?

Thank you.
