Count weekdays between two dates and exclude dates from list

Question

This code count the weekdays between two dates.

from dateutil.rrule import *
number_weekdays = rrule(WEEKLY, byweekday=(SU,MO,TU,WE,TH),
                        dtstart=datetime.datetime(2021, 5, 1),
                        until=datetime.datetime(2021, 6, 30)).count()

what should I do in order to exclude dates from a list ?

I know about 'exdate' , but I dont know how to use it in this code

Answer 1

import datetime 
from dateutil.rrule import *
rules = rruleset()

# all days to count
rules.rrule(rrule(WEEKLY, byweekday=(SU,MO,TU,WE,TH,FR,SA),
                        dtstart=datetime.datetime(2021, 5, 1),
                        until=datetime.datetime(2021, 6, 30)))

# exlude days from list
rules.exrule(number_weekdays)

rules.count()
