In a unix shell script I can do something like this to look in a
directory and get the name of a file or files into a variable :

MYFILE=`ls /home/mydir/JOHN*.xml`


Can I do this in one line in python?

Depends if you count imports.

import glob
my_files = glob.glob('/home/mydir/JOHN*.xml')

I suggest you to take a look at walk function inside the os module
[1]; IIRC, on the list you would find a discussion on how to create a
wrapper for os.walk with support for filters or wildcards.

Regards.

import os; my_files = [f for f in os.listdir('/home/mydir/') if 'JOHN' in f and 'xml' in f]

But in fact glob uses os.listdir and fnmatch.fnmatch functions
internally, so is definitely the way to go.
