Question

I would like to remove all punctuation from a filename but keep its file extension intact.

e.g. I want:

Flowers.Rose-Murree-[25.10.11].jpg
Time.Square.New-York-[20.7.09].png

to look like:

Flowers Rose Muree 25 10 11.jpg
Time Square New York 20 7 09.png

I’m trying python:

re.sub(r'[^A-Za-z0-9]', ' ', filename)

But that produces:

Flowers Rose Muree 25 10 11 jpg
Time Square New York 20 7 09 png

How do I remove the punctuation but keep the file extension?

Answer 1

There’s only one right way to do this:

1. os.path.splitext to get the filename and the extension
2. Do whatever processing you want to the filename.
3. Concatenate the new filename with the extension.
