Can someone think of an easy way to calculate the number of weekdays
between two calendar dates (in Python)?
That depends on what you mean by “weekdays”.
>>> import datetime
>>> begin_date = datetime.date(2009, 10, 9)
>>> end_date = datetime.date(2009, 10, 22)
>>> import calendar
>>> print calendar.month(2009, 10)
October 2009

19 20 21 22 23 24 25
26 27 28 29 30 31
>>> end_date - begin_date
datetime.timedelta(13)
If you're expecting to exclude Saturday and Sunday (i.e. if you expect
the above result to be 9 days instead of 13), you can use other
functions of the ‘calendar’ module; try starting with:
>>> friday_weekday = 4
>>> len([
... date for date in (
... begin_date + datetime.timedelta(days)
... for days in range((end_date - begin_date).days))
... if calendar.weekday(date.year, date.month, date.day) <=
friday_weekday])

Thanks for your help. For a non-expert at Python, that last compound
statement is pretty inscrutable. I am trying to scrute it. Wish me luck.
