Date is weekend or weekday

Date is weekend

To check if the given date is a weekend, you can use datetime.datetime.weekday() to get the day of the week as an integer. Then, you can check if the day of the week is greater than 4.

from datetime import datetime, date

def is_weekend(d = datetime.today()):
  return d.weekday() > 4

is_weekend(date(2020, 10, 25)) # True
is_weekend(date(2020, 10, 28)) # False

Date is weekday

For the opposite case (checking if the date is a weekday), you can use the same technique, but checking if the day of the week is less than or equal to 4.

from datetime import datetime, date

def is_weekday(d = datetime.today()):
  return d.weekday() <= 4

is_weekday(date(2020, 10, 25)) # False
is_weekday(date(2020, 10, 28)) # True
