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?

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"!!!

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

See strftime()
