Use regular expressions. They are part of the module "re". And if you use
them, ditch your code above, and make it just search for a pattern all the
time. Because the above is just the case of

*.ext

Use module glob.

Hi,

I wrote a small gtk file manager, which works pretty well. Until
now, I am able to select different file (treeview entries) just by
extension (done with 'endswith'). See the little part below:

self.pathlist1=[ ]
self.patternlist=[ ]
while iter:
# print iter
value = model.get_value(iter, 1)
# if value is what I'm looking for:
if value.endswith("."+ pattern):
selection.select_iter(iter)
selection.select_path(n)
self.pathlist1.append(n)
self.patternlist.append(value)
iter = model.iter_next(iter)
# print value
n=n+1

Now, I would like to improve it by searching for different 'real'
patterns just like using 'ls' in bash. E.g. the entry
'car*.pdf' should select all pdf files with a beginning 'car'.
Does anyone have an idea, how to do it?

Greetings!
Fabian

The glob module is a more direct tool based on the OP's example. The
example he gives works directly with glob. To use re, you'd have to
convert to something like "car.*\.pdf", yes?

(Of course, re offers much more power than simple globbing. Not clear
how much more the OP was looking for.)

Then I shudder to think what might have happened if you had used
re's!

Thanks for your help! glob works pretty good, except that I just
deleted all my lastet pdf files

I'm aware of the glob-module. But it only works on files. I was under
the impression that he already has a list of files he wants to filter
instead of getting it fresh from the filesystem.

In that case the best way would be to use the fnmatch module - it already
knows how to translate from car*.pdf into the right regexp. (The glob
module is like a combo os.listdir+fnmatch.filter)

I have a already a list, but I 'glob' looked so easy ... maybe it is
faster to use fnmatch. When I have time I try it out...

A different feature it had was to copy the whole home-partition
(about 19G) into one of its own directories ... the strange thing:
it just needed seconds to do that and I did not have the permission
to all files and directories! It was pretty strange! Hopefully it
was no security bug in python...
