Question

when I input python code:

today=datetime.datetime.now()
toda
today.weekday(),

Result is:

datetime.datetime(2012, 9, 18, 16, 53, 35, 124836)    
1

But, should it be 2? Anything wrong or my mistake?

Answer 1

No, today is Tuesday, and that’s weekday 1, following the documentation:

Return the day of the week as an integer, where Monday is 0 and Sunday is 6. The same as self.date().weekday(). See alsoisoweekday().

So Monday is 0, Tuesday is 1, etc.

If you want 2 for Tuesday, use .isoweekday() instead:

>>> datetime.datetime.now().isoweekday()
2

Return the day of the week as an integer, where Monday is 1 and Sunday is 7. The same as self.date().isoweekday(). See also weekday(), isocalendar().
