@pixelcowboy: I think Julien was asking how to detect the padding from a
filename, not a string with padding notation in it (which yours would work
for).
For safety, I would make the filename regex a little more specific, in case
there are multiple digit sequences in a filename (DI/EDL-generated names can
be nightmarish like that). Here's one option:
import re
image = 'awesome.v.001.0101.exr'
match = re.search('(\d+)\.\w+$', image)
print len(match.group(1)) if match else None
Obviously it's hard to come up with something that's totally bulletproof,
but it's nice to eliminate as many special cases as possible early on.

You can also use a wider pattern like :
r'(%+\d+d)|(#+)|(%d)'
to catch a few more cases. I highly recommend that you account for
these as you might run into problems later.

import re
result = None
image = 'awesome.0101.exr'
number = re.search('\.(\d+)\.', image)
if number:
result = len(number.group(1))
print result
I would use regex to pull that information out.

Hello,
It's more a general python question, but image related.
I'm looking at detecting the padding of a filename let's say something
like
" Filename.001.exr" would return 3
I'm having a hard time to find this answer on the web
Thanks for your help
