How do I Join all files in os.listdir after re.sub?

wxPython Users

I have a multiline TextCtrl I want to output a bunch of files with re.sub.

This box is just for reading os.listdir for testing:

    if

self.filenames:

        path =

self.dirname

dirList=os.listdir(path)

        for

self.filename in dirList:

                f

= self.filename

                print

f ## reads all files

               self.PracInput.SetValue(re.sub(self.PracRemove.GetValue(),self.PracReplace.GetValue(),f))

SetValue is reading only the last file. I understand that. So how can I use something like . join to
re.sub all the files just for reading?

That makes sense, no? You are in a loop and “f” will always only
contain the name of one file.

Hi,
I guess, the SetValue method of a TextCtrl only accept strings, you
can join the list like: "\n".join(myFiles).
Note, that os.listdir only returns the data for the respective path,
i.e. not some deeper nested directories, but you probably can control
or assume the directory structure, you are accessing..

hth,

Good catch, thanks for correcting me.

I implemented:
myFiles.append(newF)
self.PracInput.SetValue(str(“\n”.join(myFiles)))
Works fine now.
Thanks werner,vbr
One more question, is there a way to mark this post as resolved?
