Something to remember.

But in this case I also need the previous month. So I have:
    files           = sorted(os.listdir('.'))
    p               = re.compile('actions-2015-05-[0-9][0-9].sql$')
    current_month   = [ file for file in files if p.match(file) ]
    p               = re.compile('actions-2015-04-[0-9][0-9].sql$')
    previous_month  = [ file for file in files if p.match(file) ]

Of-course I will not hard-code the months in the real code.
