Is there an existing function or "conversion" that would allow for getting yesterday's date with ...time...???

Thank you

    Much simpler :) 

     import datetime print "today:", datetime.date.today() print "yesterday:", datetime.date.today()-datetime.timedelta(1)

        Use timedelta (see the Python documentation).

    Hello
    You are -1 on today's date :)

    It's not that simple if you want a date in the format "20070702"!
    --------------------------------------------------------------------------------

    today = time()

    # 86400 = 24 h x 3600 seconds => 1 day in seconds!
    yesterday = today - 86400
    formatted = gmtime(yesterday)

    if len(str(formatted[1]))<2:
    first = "0" + str(formatted[1])
    else:
    first = str(formatted[1])
    if len(str(formatted[2]))<2:
    second = "0" + str(formatted[2])
    else:
    second = str(formatted[2])

    concat = str(formatted[0]) + first + second

    === > because otherwise it could result in "200772"!!!

    See strftime()
