用python实现时间的动态（动态时钟）+ 算出某年某月星期几的所有日期

一个玩得好的朋友突然大晚上的给我布置作业，吓得我精神抖擞。他的原话是：

感觉发现新大陆了，利用小海龟画的，上次玩海龟已经是几个月之前的事情了

算出某月星期几的所有日期

from datetime import date, timedelta, datetime
import calendar# 输入想要获取的年月份
cal = calendar.month(2020, 9)
print(cal)m = datetime.now().month
y = datetime.now().year
ndays = (date(y, m + 1, 1) - date(y, m, 1)).days
day_one = date(y, m, 1)
last_day = date(y, m, ndays)
delta = last_day - day_one
data_list = []
for i in range(delta.days + 1):p = (day_one + timedelta(days=i)).strftime('%Y-%m-%d')pp = datetime.strptime(str(p), '%Y-%m-%d')one = pp.isoweekday()print(type(one), one)if one == 1:  #此处的1为星期一d2 = pp.strftime('%Y-%m-%d')data_list.append(d2)print("2020年9月份所有的星期一的日期为", data_list)#实时获取当前时间 转换为str字符串
now = datetime.now()
print('当前时间为 :', now)
