Hi Mike,
Kent gave you the answer to the question you asked. But, for what you
are doing, I'd think about something sort of along the lines of Bob's
suggestion.
The way below avoids going through datetime objects:
>>> t = time.time()
>>> t -= 5 * 24 * 60 * 60
>>> # t is now 5 days back from current seconds from epoch
>>> def older_than_n_days(n, time_stamp):
return time.time() - time_stamp < n * 24 * 60 * 60
>>> for i in range(3, 8):
print older_than_n_days(i, t)
False
False
False
True
True
>>>
Best,
Brian vdB
