Not the most elegant piece of code on earth,
but this piece of code works for me (cut-and-pasted
directly from a working project, so doesn't
*exactly* match your requirement).
<code>
def deltastamp (now, then):
def pluralise (base, n):
if n > 1:
return "%d %ss" % (n, base)
else:
return "%d %s" % (n, base)
if now > then:
output_format = "%s ago"
delta = now - then
else:
output_format = "in %s"
delta = then - now
days = delta.days
if days <> 0:
wks, days = divmod (days, 7)
if wks > 0:
output = pluralise ("wk", wks)
else:
output = pluralise ("day", days)
else:
mins, secs = divmod (delta.seconds, 60)
hrs, mins = divmod (mins, 60)
if hrs > 0:
output = pluralise ("hr", hrs)
elif mins > 0:
output = pluralise ("min", mins)
else:
output = pluralise ("sec", secs)
return output_format % output
</code>
