Hi,
How can I check for the xistence of any file that matches a wildcard?
For example: ppis-*.iss
os.path.exists( ) doesn't expand the wildcard...

Use glob.glob and then os.path.exists in a loop.

have you taken a look at glob.glob?
import glob, os
dirname="."
filespec="ppis-*.iss"
print glob.glob(os.pa th.join(dirname , filespec))

Wouldn't the glob.glob only return files that actually exist?

Sure, but isn't that what he wants? He wrote, "the [existence] of any
file that maches a wildcard." He's obviously talking about existing
files.
Besides, what else could expanding a wildcard mean except enumerating
every possible match?

Sure, but then what? Maybe the OP was only interested if _any_ matches existed. E.g.,
pattern = 'ppis-*.iss'
if glob.glob(patte rn): print 'there is at least one file matching %r'%pattern
else: print 'no files match the %r pattern'%patter n
might be reasonable to do in some context -- without looking at the actual matches, if any.
Maybe this is what Jeremy had in mind (a lot of mind reading around here ;-)

Yes, that exactly what I wanted, and the glob trick works fine. Thanks. :-)

Ah, you misunderstand; my problem was with the "and then
os.path.exists in a loop" part, since, by definition, the files
returned by glob.glob will exist :) I was just trying to kindly point
out that os.path.exists isn't needed for his purposes. I guess I
could've been more clear :)

I've got a webapp which is behaving oddly. I want to include an image on
the webpage, but only if the physical file exists; if it doesn't, I
don't want an img element to generate an ugly blank box. I know the
physical location of the image(s) in question, and figured I'd use
os.path.exists to see if each file exists. A quick test in the
interpreter yields:
>>> os.path.exists(u'S:/Scans/Projects/2004/TJ/04TJ0267.jpg')
True

Dearest Colleagues,
I was suddenly having a sharp pain in locating information about a

In Java, I can preprocess, via a filter, some HTTP requests before
answering to the client. Please allow me to show and example since it
will illustrate the point well.

For most users, this new feature is actually very convenient. If you want to control the update process,...
