os.path.isfile and wildcard for directory name

[smainklh]

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 !

Given

$ mkdir yadda{1..10}
$ touch yadda{5,7}/alpha
$ mkdir yadda{2,4}/alpha

You can get a list of candidates with
['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']
