Directory Walker for Python
I am currently using the directory walker from Here
import os class DirectoryWalker: # a forward iterator that traverses a directory tree 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: # got a filename fullname = os.path.join(self.directory, file) if os.path.isdir(fullname) and not os.path.islink(fullname): self.stack.append(fullname) return fullname for file in DirectoryWalker(os.path.abspath('.')): print file
This minor change allows you to have the full path within the file.
Can anyone help me how to find just the filename as well using this? I need both the full path, and just the filename.

Why do you want to do such boring thing yourself?
for path, directories, files in os.walk('.'): print 'ls %r' % path for directory in directories: print ' d%r' % directory for filename in files: print ' -%r' % filename
'.' d'finction' d'.hg' -'setup.py' -'.hgignore' './finction' -'finction' -'cdg.pyc' -'util.pyc' -'cdg.py' -'util.py' -'__init__.pyc' -'__init__.py' './.hg' d'store' -'hgrc' -'requires' -'00changelog.i' -'undo.branch' -'dirstate' -'undo.dirstate' -'branch' './.hg/store' d'data' -'undo' -'00changelog.i' -'00manifest.i' './.hg/store/data' d'finction' -'.hgignore.i' -'setup.py.i' './.hg/store/data/finction' -'util.py.i' -'cdg.py.i' -'finction.i' -'____init____.py.i'
But if you insist, there's path related tools in os.path, os.basename is what you are looking at.

>>> import os.path >>> os.path.basename('/hello/world.h') 'world.h'
Rather than using '.' as your directory, refer to its absolute path:
for file in DirectoryWalker(os.path.abspath('.')): print file
Also, I'd recommend using a word other than 'file', because it means something in the python language. Not a keyword, though so it still runs.
As an aside, when dealing with filenames, I find the os.path module to be incredibly useful - I'd recommend having a look through that, especially
Normalises paths (gets rid of redundant '.'s and 'theFolderYouWereJustIn/../'s)

os.path.dirname()? os.path.normpath()? os.path.abspath()?
This would also be a lovely place to think recursion.Answered by: Darcy841 | Posted: 07-01-2022
Just prepend the current directory path to the "./foo" path returned:

ftp - Using Python's ftplib to get a directory listing, portably
You can use ftplib for full FTP support in Python. However the preferred way of getting a directory listing is: # File: ftplib-example-1.py import ftplib ftp = ftplib.FTP("www.python.org") ftp.login("anonymous", "ftplib-example-1") data =  ftp.dir(data.append) ftp.quit() for line in data: print "-", line Which yields: $ python ftplib-example-1.py - total 34 - dr...

java - Mixed language source directory layout
We are running a large project with several different languages: Java, Python, PHP, SQL and Perl. Until now people have been working in their own private repositories, but now we want to merge the entire project in a single repository. The question now is: how should the directory structure look? Should we have separate directories for each language, or should we separate it by component/project? How well does pyt...
import - Current working directory no longer inherited from calling process from python 2.5 onwards?
I updated my python version on windows 2003 server from 2.4 to 2.5. In 2.4 I could import a file "sub1.py" from a subdirectory c:\application\subdir\ like this: import sub1 as long as the calling script main.py that lives in c:\application was started like this: c:\application\subdir>python ..\main.py But in 2.5 it no longer works for me:
How do I tell a file from directory in Python?
When using os.listdir method I need to tell which item in the resulting list is a directory or just a file. I've faced a problem when I had to go through all the directories in this list, and then add a file in every single directory. Is there a way to go through this list and remove all files from it? If it isn't possible to do with os.listdir, what method should I use instead? Thanks.
