I use fnmatch:
for path, dirs, files in os.walk(root):
# exclude dirs
dirs[:] = [os.path.join(path, d) for d in dirs
if not fnmatch.fnmatch(d, exclude)]
# exclude files
files = [os.path.join(path, f) for f in files
if not fnmatch.fnmatch(f, exclude)]
where
exclude=r’.*’

Somebody on the tutor mailing list wants to match
"all files and direcories in this directory that do not start
with a ."
The filetypes option seems only to want patterns to match, not
patterns to exclude. Is my pattern matching magic just off, or
is there no way to exclude things in a tkFileDialog?
puzzled,
Laura

Hi,
I've found this little gem in the Tk docs
https://www.tcl.tk/man/tcl8.4/TkCmd/getOpenFile.htm#M13
From what I see "file patterns" in the file dialog are not "regex
patterns" and do not support special characters. Only things that work
are:
1) * - any extension
2) "" - files without extension
3) literal extension without wildcard chars
Unfortunately it looks like there is no simple way to filter out hidden
files.
Check out this answer

Pawel Mosakowski

Thank you. Looks like it will be necessary to construct a new
widget. I'm surprised ...

More than I. I can understand your disappointment that
file-dialogue "file patterns" have such a rudimentary
syntax; I speculate with considerable confidence that
the authors acted with sh as the model most in their
mind. You're quite right, Laura, that the elements are
at hand to allow you to construct your own variant. If
the history of getOpenFile truly interests you, act
quickly: while we can get to the authors now, it won't
be many cycles more before their memories and records
senesce irretrievably.
