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

话不多说，上代码！

动态时钟

from turtle import *
from datetime import *


# 移动到指定位置
def skip(step):
    penup()
    forward(step)
    pendown()


# 画指针
def drawpointer(name, length):
    reset()
    skip(-length * 0.1)
    begin_poly()
    forward(length * 1.1)
    end_poly()
    handForm = get_poly()
    register_shape(name, handForm)


# 初始化
def init():
    global hrpointer, minpointer, secpointer, weektext
    # 设置turtle Logo模式，朝北
    mode("logo")
    drawpointer("hrpointer", 90)
    drawpointer("minpointer", 130)
    drawpointer("secpointer", 140)
    hrpointer = Turtle()
    hrpointer.shape("hrpointer")
    minpointer = Turtle()
    minpointer.shape("minpointer")
    secpointer = Turtle()
    secpointer.shape("secpointer")
    secpointer.pencolor("red")
    for pointer in hrpointer, minpointer, secpointer:
        pointer.shapesize(3, 1, 1)
        pointer.speed(0)
    # 文字输出
    weektext = Turtle()
    weektext.hideturtle()
    weektext.penup()


# 设置表盘形状
def setupClock(radius):
    #绘制表的外框
    reset()
    #  clockPanel = Turtle()
    pensize(7)
    pencolor("blue")
    for i in range(60):
        skip(radius)
        if i % 5 == 0:
            forward(20)#画长刻度线
            skip(-radius - 20)#回到中心点
        else:
            dot(5)
            skip(-radius)
        right(6)


# 星期文本
def Week(t):
    week = ["星期一", "星期二", "星期三", "星期四", "星期五", "星期六", "星期日"]
    return week[t.weekday()]


# 日期文本
def Date(t):
    y = t.year
    m = t.month
    d = t.day
    return "%s %d %d" % (y, m, d)


# 绘制表针动态显示
def tick():
    t = datetime.today()
    second = t.second + t.microsecond * 0.0000001
    minute = t.minute + second / 60.0
    hour = t.hour + minute / 60.0
    secpointer.setheading(6 * second)
    minpointer.setheading(6 * minute)
    hrpointer.setheading(30 * hour)
    tracer(False)
    weektext.forward(65)
    weektext.write(Week(t), align="center", font=("Courier", 14, "bold"))
    weektext.back(130)
    weektext.write(Date(t), align="center", font=("Courier", 14, "bold"))
    weektext.home()
    tracer(True)
    # 间隔100ms调用一次
    ontimer(tick, 100)


def main():
    #打开/关闭海龟画，并为更新图纸设置延迟
    tracer(False)
    init()
    setupClock(160)
    tracer(True)
    tick()
    mainloop()


if __name__ == '__main__':
    main()

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)

运行结果
