import random
import datetime

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)
