Python path walk list directories and files Print E-mail
I needed to crawl a directory structure and get a list of all the files with their absolute location, I think the easiest way to do this is with os.path.walk. The syntax is a little confusing at first, but it works fine and I end up with the list of all files with their folders from whatever location I start at.



def check(arg,dirname,fnames): #This is called recursivly by os.path.walk until all paths have been walked
                                                             #Also it gets the current dir and all the filenames in the dir each time
      for file in fnames: #Then I iterate throught all the filenames it gets
         arg.append(os.path.join(dirname,file)) #and append them with their directory to the overall list
 
os.path.walk("./",check, arglist) #Call this and all the recursion starts
 

So os.path.walk calls itself on every folder pushing the folder and its list of files to my  function check. Check then adds the full filename to arg, which is passed recursivly throught the walk.

print arg

Will list out all the files and directories.
