Another solution is proposed by Christian Heimes: "implement __int__
and __float__ on timedelta objects: int(timedelta) -> seconds,
float(timedelta) -> seconds.micros".

This solution only answer to the need "conversion to seconds" (which is the 
most common case). To get week, you would have to write:
   int(dt) / (3600*24*7)
which feels me less natural (pythonic?) than:
   dt // timedelta(days=7)
