Given
$ mkdir yadda{1..10}
$ touch yadda{5,7}/alpha
$ mkdir yadda{2,4}/alpha
You can get a list of candidates with
>>> import glob
>>> candidates = glob.glob("yadda*/alpha")
>>> candidates
['yadda5/alpha', 'yadda2/alpha', 'yadda4/alpha', 'yadda7/alpha']
and then use isfile() to find the actual files:
>>> import os
>>> [f for f in candidates if os.path.isfile(f)]
['yadda5/alpha', 'yadda7/alpha']

Hello,

You can get the contents of a directory with os.listdir and filter
with fnmatch.fnmatch more or less as in the example from the
documentation:
-
import fnmatch
import os
for file in os.listdir('.'):
if fnmatch.fnmatch(file, '*.txt'):
print file

os.path.isfile and wildcard for directory name
Hi everyone, I'm just beginning to learn python language and i'm trying to do something and i can't figure it out. I want to test if a file exists but my path contain a directory name that differs from a server to another. In shell i would have done something like that : #!/bin/bash mypath=/dire*/directory02/ myfile=filename myfile=toto if [ -f $mypath/$myfile ] then echo "File $file exists" fi How can i do the same thing (wildcard in a directory name) in python please ? Thanks for your help ! Smaine -- http://mail.python.org/mailman/listinfo/python-list
