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".
+++++++++++++++++++++++++++++++++++
#!/usr/bin/python -u
import sys, time
from os import listdir, unlink
from os.path import isdir, isfile, islink, join, getmtime
deldir = "C:\some\Dir"
delFileType = ".txt"
# -------------------------------------
def del_entry(_name):
try:
if isdir(_name):
print "This is a directory, do nothing."
else:
#print "now"
unlink(_name) # or remove(_name)
sys.stdout.write("Delete FILE %s\n" % (_name))
except IOError:
sys.stderr.write("Cannot delete %s\n" % (_name))
# -------------------------------------
def list_dir(_dir,_action):
if not isdir(_dir):
print "%s is not a directory" % (_dir)
return
for file in listdir(_dir):
path = join(_dir, file)
if isdir(path):
list_dir(path, _action)
else:
if path.rfind(delFileType) != -1:
#print path
_action(path)
# -------------------------------------
# Run it
list_dir(deldir, del_entry)

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.
