Q1:输入日期，判断这一天是这一年的第几天
def dayofyear():
year = input("输入年份: ")
month = input("输入月份: ")
day = input("输入日期: ")
date1 = datetime.date(year=int(year), month=int(month), day=int(day))
date2 = datetime.date(year=int(year), month=1, day=1)
return (date1 - date2).days + 1
Q2:打乱一个已经排好序的list对象
alist = [1, 2, 3, 4, 5]
random.shuffle(alist)
print("alist:", alist)
if __name__ == '__main__':
date = dayofyear()
print("date:", date)
