To get a list of files in a given directory one can use glob.glob and
The OP had a different problem. He wanted to find a config file of
known name that could be in one of several locations.
os.path.isfile
from os.path import isfile
from glob import glob
files_in_var_tmp = [f for f in glob('/var/tmp/*') if isfile(f) ]
For several directories iterate over the dirs and add the resulting list of
files.
tmp_files = []
for dir in ['/tmp', '/var/tmp']:
... tmp_files += [f for f in glob(dir + '/*') if isfile(f) ]

It occurs to me that it might be useful if Python provided a
function to search for a file with a given name in various
directories (much as the import.import_lib function searches for
a module in the directories in sys.path).
This function would perhaps be best placed in the os.path or os
modules.
To start the ball rolling, I offer this version:
consider: os.walk, glob.glob, Path.glob
I have. None of these are appropriate.
os.walk iterates *recursively* over a *single* directory and its
subdirectories.
pathlib.Path.glob so far as I can make out (I have never used pathlib)
does much the same.
glob.glob (so far as I can make out) does a *wildcard* search for
directories matching a *single* pattern.
My suggestion needs a *non-recursive* search for a *file* in a *list*
of
*non-wildcarded* directories.
They don't give you "search in a list of directories" intrinsically, but
that's simple loop, bailing out on a match, no?
But they all read directories. For Rob's purpose this isn't necessary.
He just needs to test a fixed number of locations. Reading even one
directory (muss less recursively scanning a whole tree like os.walk
does) is just pointless extra work.
