Comments on: Python: iterate (and read) all files in a directory (folder)

Ahh… My *.* as opposed to a * had it so it wasn’t looking at folders, thus the problem. Thanks again!

Dan,

script below seems to work perfectly for me:


import os, glob

def scandirs(path):
    for currentFile in glob.glob( os.path.join(path, '*') ):
        if os.path.isdir(currentFile):
            print 'got a directory: ' + currentFile
            scandirs(currentFile)
        print "processing file: " + currentFile

scandirs('Desktop')

Basically, I’ve changed the ‘*.*’ wildcard to just ‘*’.

Bogdan,

Thanks for the help. I’m still not getting the code to look at the directories within the path. Here’s my code, it still only looks at the files under the initial path.


def scandirs(path):
    for currentFile in glob.glob( os.path.join(path, '*.*') ):
        if os.path.isdir(currentFile):
            scandirs(currentFile)
        print "processing file: " + currentFile

scandirs('XML/')

Make that code into a function – e.g. scan_dirs(path) – and add a single line of code to it (pseudocode below):
if is_directory(infile): scan_dirs(infile)

This will do exactly what you want.

Is there a way to change this script so that it also runs through sub-directories under the given path name?

import os, glob
path = ‘./’
for infile in glob.glob( os.path.join(path, ‘*.*’) ):
print(“current file is: ” + infile)

#lists all files in directory script is in

This was exactly what I was looking for!

import os, glob

def dir(path):
for infile in glob.glob( os.path.join(path) ):
print “current file is: ” + infile

path = dir(raw_input(“Enter the path: “))

Dt, thanks, I’ve updated the code.

works just fine for me, only important change to the code that i had to make was turning print into a function because im using python 3.0, i also set it to read files with *all* extensions.

import os, glob

path = ‘insert your own path you lazy bastards ‘

for infile in glob.glob( os.path.join(path, ‘*.*’) ):
print(“current file is: ” + infile)

it should. you might want to modify the example to suit your exact needs – this example assumes there is ’sequences’ folder with at least one .fasta file – if that’s not true, then – evidently – you are not going to see this script work, be it windows or linux.
