python- selecting dates

[danholding]

hiya guys n girls,

i am making a prgram where it sorts a list of files and pulls the 6 most recent files..

that is fine but i need it to pull 6 different dates ie...

(this is what it does now
test1 - 24/06/10
test2 - 24/06/10
test3 - 24/06/10
test4 - 28/06/10
test5 - 28/06/10
test6 - 29/06/10
)
(this is what i want it to do
test1 - 19/07/10
test2 - 14/07/10
test3 - 09/07/10
test4 - 02/07/10
test5 - 30/06/10
test6 - 29/06/10
)
i have this code which pulls the last 6 modifed dates if this helps

for lastmod_seconds, path in date_file_list[:6]:
    folder, file_name = os.path.split(path)
    # convert seconds to time tuple
    lastmod_tuple = time.localtime(lastmod_seconds)
    # convert time tuple to MM/DD/YYYY HH:MM:SS format
    file_date = time.strftime("%m/%d/%y %H:%M:%S", lastmod_tuple)
    print "%-40s %s" % (file_name, file_date)

[woooee]

If I understand the question, you want to print file dates that have not already been printed so you have to use some sort of container, a list for example, which contains the dates already printed, and print only if the date has not already been used.
