Re: Changing a value for each folder while traversing a file system
Perfect. That's exactly what I wanted. Thanks.
For those reading this later on, the following script will crawl
through a directory, select all the text files, dump them into seperate
numbered html files in the parent directory (in which the python script
is executed). In this example, the first line of the text file is
placed into a table with a randomly colored background. With a little
work, the text files can be complexly formatted, each folder can be
color coded, etc.

Re: Changing a value for each folder while traversing a file system
No, that doesn't work. Though, leaving the random snippet about the for file in DirectoryWalker(.): line, it does leave all files the same value, rather than switching the value for every single file. The problem is, the value is shared accross every folder. -- http://mail.python.org/mailman/listinfo/python-list

That seems logical, but the syntax doesn't work. I keep getting the error: 'module object' has no attribute 'dirname' -- http://mail.python.org/mailman/listinfo/python-list

What I can't figure out is how to trigger a change in the background value for each folder change (not each file), so that text is color-coded by folder. I have tried to integrate the following snippet into the directory walker, so that I could later write it to the file as text: color = random.choice([#99, #CC, #99]) That method didn't work, does anyone else have a suggestion? #! /usr/bin/python import glob import fileinput import os import string import sys index = open(index.rtf, 'w') class DirectoryWalker: # a forward iterator that traverses a directory tree, and # returns the filename def __init__(self, directory): self.stack = [directory] self.files = [] self.index = 0 def __getitem__(self, index): while 1: try: file = self.files[self.index] self.index = self.index + 1 except IndexError: # pop next directory from stack self.directory = self.stack.pop() self.files = os.listdir(self.directory) self.index = 0 else: # get a filename, eliminate directories from list fullname = os.path.join(self.directory, file) if os.path.isdir(fullname) and not os.path.islink(fullname): self.stack.append(fullname) else: return fullname for file in DirectoryWalker(.): # divide files names into path and extention path, ext = os.path.splitext(file) # choose the extention you would like to see in the list if ext == .txt: print file file = open(file) fileContent = file.readlines() # just for example, let's say I want to print the color here as if in an html tag... index.write(color) for line in fileContent: if not line.startswith(\n): index.write(line) index.write(\n) index.close() Add a color attribute to the DirectoryWalker class, change it when you change directories, return it with the fullname. Change your for loop like so: for color, file in DirectoryWalker(.): # ... I think that should work. HTH, ~Simon -- http://mail.python.org/mailman/listinfo/python-list
