current week / weeks in year - best practice

[Aljosa Mohorovic]

i use this to find out current week and total number of weeks for
current year:
now = datetime.now()
weeks_in_year = int(date(now.ye ar, 12, 31).strftime("% W"))
current_week = int(date(now.ye ar, now.month, now.day).strfti me("%W"))

is this the best way or is there a better way?

Instead of datetime.now() use date.today(), which removes a lot of
boilerplate.

int(date.today( ).strftime("%W" ))

Apart from that, I think it's the way to go.

what if i know current context week = 20 (example), what would be the
best way to get datetime objects for first and last day of current
context week?
by "current context week" i don't mean current week for current year
but current week when program is iterating all weeks in year.

if w = current context week and now is current datetime object this
is how i calculate days:
first_day = datetime.strpti me("%s %s" % (now.year, str((w-1)*7)), "%Y
%j")
last_day = first_day + timedelta(days= 6)

any comments on this?

One of the problems is that "current week of the year" is not a
well-defined term. Some companies define the first week as the week that
contains January 1. Some companies define the first week as the first full
week, so that a partial Jan 1 week is actually part of the previous year.
And you get the whole "does the week start on Sunday or Monday" debate as
well.

You need to make sure that the datetime functions match your business
rules.
