I don't know.

1. Convert datetime object to timestamp object.
2. Convert previous Monday or Sunday to timestamp (is in seconds).
3. Subtract one from another and divide them by number of seconds in
day (or whatever you want).

I guess 1 PM is more like 6.54 or even 5.54 or 4.45.
1) int(5.54) => 5.
2) {0: 'Sunday', 1: 'Monday'....
3) round((5.54-int(5.54))*24) -> 13 ...

Don't be lazy ;-)
