Hello all!
There is a class Calendar in calendar.py in standard libriary.
class Calendar(object):
"""
Base calendar class. This class doesn't do any formatting. It simply
provides data to subclasses.
"""
def __init__(self, firstweekday=0):
self.firstweekday = firstweekday # 0 = Monday, 6 = Sunday
def getfirstweekday(self):
return self._firstweekday % 7
def setfirstweekday(self, firstweekday):
self._firstweekday = firstweekday
firstweekday = property(getfirstweekday, setfirstweekday)
As far as I understand, even if user enters inappropriate firstweekday
parameter (bigger than 6) during instansiation of the Calendar, the Calendar
swallows it (and latter returns correct firstweekday value due to %7 in
getfirstweekday method).
So, the question is why not explicitly raise ValueError if user enters the
firstweekday parameter bigger that 6 (with accordance with the Zen). Am I
missing something?
Thank you in advance
Best regards, Aynur
