如何计算提供日和月的星期几

Question

这个计划严格规定在2014年。不过，我想知道我的方向是否正确。到目前为止，我得到的是：

def day(d,m): # Function for determining day name for a given date.
    """Where m is an integer from 1 through 12 expressing a month, and d is an integer from 
    1 through 31 expressing the day-part of a date in 2014."""

    day = ['Su', 'Mo', 'Tu', 'We', 'Th', 'Fr', 'Sa']
    weekday = (d + (2.6*m - 0.2) -2*20 + 2014 + (2014//4) + (20//4))
    return day[weekday]

Answer 1

Don't reinvent the wheel：

>>> import datetime
>>> datetime.datetime(2014, 2, 16).strftime('%a')
'Sun'

---

Or as a number：

^{pr2}$

然后您可以将其传递到您的day列表中
