python - 不使用 IF 语句

Question

def get_weekday(d1, d2):
    ''' (int, int) -> int
    The first parameter indicates the current day of the week, and is in the 
    range 1-7. The second parameter indicates a number of days from the current 
    day, and that could be any integer, including a negative integer. Return 
    which day of the week it will be that many days from the current day.
    >>> get_weekday(0,14)
    7
    >>> get_weekday(0,15)
    1
    '''
    weekday = (d1+d2) % 7
    if weekday == 0:
        weekday = 7
    return weekday

如何在不使用 if 语句的情况下解决这个问题？

顺便说一句，星期日是 1，星期一是 2，....星期六是 7

Answer 1

怎么样

weekday = (d1-1+d2) % 7 + 1
