[Python] How to get yesterday's date

tata-titi -  
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)

      Hey,
      so how do you indicate the date from one month ago?

      @getnateUse 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"!!!

        If you want a date in the format "20070702"!

        See strftime()
