Python Turtle 画动态圣诞贺卡

Python画动态圣诞贺卡

兔兔大人的第一个博客

圣诞节制作了一款动态贺卡，有圣诞树，点亮彩灯，飘雪以及文字效果。这是我的第一个博客作品，希望大家喜欢。

效果如下，有动态效果。

代码如下：

# -*- coding: utf-8 -*-
import turtle as T
import random
import time
	
# 绘图区域
t = T.Turtle()
# 画布大小
w = T.Screen()
t.hideturtle()  # 隐藏画笔
t.getscreen().tracer(5, 0)
w.screensize(bg='maroon')
t.left(90)
t.up()
t.forward(280)
t.down()
t.pensize(3)

# 画五角星
n=100
t.color("orange","yellow")
t.begin_fill()
