python - Using datetime and dateutils to calculate a journey -

i using dateutils forecast arrival time on journey.

• i can represent start time datetime object. that's nice.

• i can represent journey_time timedelta. that's nice

problem: what's unclear me how shall represent meeting time applies weekday?

considerations: if use datetime object, have declare meeting time particular date. means have update every day. rather tedious. i'd prefer notation allows me "any {mon,tue,wed,thu,fri,sat,sun}-day" @ '09:00:00'

pseudo example

import datetime import dateutils  # setting start time datetime object. start = '2015-08-19t08:00:00'  # going home work: mondays = 3000  # seconds timedelta.  arrival = start + journey_time  # calculating arrival time.  # recording first meeting... meeting = '09:00:00'  # <--------------how should represent value?  arrival < meeting:   # <------------- important check. # should return true, if can make it. 

i suggest represent meeting time datetime.time object has no date attributes. expanding on pseudocode:

import datetime  # setting start time datetime object.  start = datetime.datetime(2015, 8, 19, 8)  # going home work: mondays = datetime.timedelta(seconds=3000)  # seconds timedelta.  arrival = start + mondays  # calculating arrival time.  # recording first meeting... meeting = datetime.time(9)  if (arrival.hour*60)+arrival.minute < (meeting.hour*60)+meeting.minute:     #code here 

the if statement checks number of minutes elapsed in day compare them. in seconds if required
