How to tell how many weeks apart two datetimes are?

[Roy Smith]

How do you tell how many weeks apart two datetimes (t1 and t2) are?
The "obvious" solution would be:

weeks = (t2 - t1) / timedelta(days=7)

but that doesn't appear to be allowed. Is there some fundamental
reason why timedelta division not supported?

It works for python 3(.2):
1332.0

Seems to be supported in Python 3.3, but not in 2.7.

Seems to be supported in Python 3.3, but not in 2.7.

From the docs:

Changed in version 3.2: Floor division and true division of a
timedelta object by another timedelta object are now supported, as are
remainder operations and the divmod() function. True division and
multiplication of a timedelta object by a float object are now
supported.

Try this:

weeks = (t2 - t1).days / 7

Try this:

weeks = (t2 - t1).days / 7

You beat me to it...
