Hi folks,
I have a little script that sits in a directory of images and, when ran,
creates thumbnails of the images. It works fine if I call the function
inside the program with something like "thumbnailer("jpg), but I want to use
a regular expression instead of a plain string so that I can match jpeg,
jpg, JPEG etc.
Here's the script:
---
#!/usr/bin/env python
from PIL import Image
import glob, os, re
size = 128, 128
# takes an extension (e.g. jpg, png, gif, tiff) as argument
def thumbnailer(extension):
#glob the directory the script is in for files of the type foo.extension
for picture in glob.glob("*." + extension):
file, ext = os.path.splitext(picture)
im = Image.open(picture)
im.thumbnail(size, Image.ANTIALIAS)
im.save(file + ".thumbnail." + extension)
jpg = re.compile("jpg|jpeg", re.IGNORECASE)
thumbnailer(jpg)
---
And here's the error:
---
Traceback (most recent call last):
File "./thumbnail.py", line 19, in ?
thumbnailer(jpg)
File "./thumbnail.py", line 11, in thumbnailer
for picture in glob.glob("*." + extension):
TypeError: cannot concatenate 'str' and '_sre.SRE_Pattern' objects
---
It looks to me like the conversion to a regex object instead of a plain
string is screwing up the file glob + extension concatenation. Is there a
simple way to accomplish what I'm trying to do here and get rid of that
error?
Thanks!
