Not the case here.  the function is being called by the following code
snippet:

    files = []
    sampdef = {}
    for i in range(2,len(sys.argv)):
        files.append(sys.argv[i]+("/%04s/%02s" % (year, month)) +
"/%d/%02d%02d.log")
        sampdef[('+', i)] = []
        sampdef[('-', i)] = []

    print files

    samples = {}
    skip = 1

    minCache = {}

    names = ingestMapfile("/u/dgilbert/rules/hadrian3.rules.map")

    samples = parseLogs(files, names)

... and "print files" produces the following output:

['2/2001/05/%d/%02d%02d.log', '3/2001/05/%d/%02d%02d.log']
