Answer 1

If you create a function to do the date maths, it gets almost as nice as your original implementation:

def next_month(this_year, this_month):
  if this_month == 0: 
    return (this_year - 1, 12)
  else:
    return (this_year, this_month - 1)

this_month = datetime.date.today().month()
this_year = datetime.date.today().year()
for m in range(0, 10):
  yield (this_year, this_month)
  this_year, this_month = next_month(this_year, this_month)
