硬核浪漫！圣诞节给对象送礼的5个最没用小技巧
毕导官方账号《圣诞节里吃饺子》
腊月廿四平安夜，过了今晚过圣诞。
圣诞虽说是洋节，吃口饺子也和谐。
圣诞擀了饺子皮，福禄寿喜都到齐。
圣诞饺子蘸着醋，来年出门不迷路。
圣诞饺子不吃饱，大年三十没棉袄。
不到长城非好汉，不吃饺子无圣诞。
无！！！圣！！！！诞！！！
（定场诗完）
今年的圣诞节恰逢周末，许多观众朋友结束了一周辛勤的学习和工作，正好借此机会约上对象或者是正在追的对象出去玩耍。
小冷风一吹，小手手一牵，小礼物一送，小浪漫气氛一起，事情就这么成了
但送什么礼物、怎么送礼物，是一门艺术！在当今社会，人们对礼物早已不再满足于物质层面的需求，而更追求精神层面的仪式感。
你送个苹果，今晚吃完，过三天对方已经不记得你送过啥了。你送束花，现在的人都手笨，哪还会养花？你送个几万块的名表名包，对方会觉得你只是想用金钱收买自己，格局又小了（这一条我没试过所以不太确定，但我猜应该是这样）。
在我看来，送礼最重要的是创意！一个好的创意，既能展现你的特点，又能给对方留下深刻印象，是非常加分的。
考虑到我的粉丝群体通常比较喜欢理工科的硬核浪漫。今天，毕老师就来给大家分享5个很适合在圣诞节送的礼物，绝对好用，不好用我论文送你二作。
一、用Python写一张贺卡
Python是一门面向对象编程的语言，天然很适合用于面向你的对象送礼物。
我在这里帮大家找到了一段用Python生成圣诞贺卡的程序，来自https://www.codetoday.co.uk/christmas。只要放到编译器里直接一run，就会出现一张非常温馨可爱的圣诞贺卡！相信我，没有人能抵抗如此用心的设计。
话不多说我们直接上代码！

import turtle
import random
import time
width = 600
height = 500
window = turtle.Screen()
window.setup(width, height)
window.bgcolor("sky blue")
window.title("Merry Christmas")
snowball_rate = 1, 3
snowball_size = 5, 15
wind_change = 1, 5
max_wind = 3
# Create all circle-shaped objects
def make_circle(turtle_name, x, y, size, colour):
turtle_name.color(colour)
turtle_name.penup()
turtle_name.setposition(x, y)
turtle_name.dot(size)
# Create new snowballs and store in list
list_of_snowballs = []
def make_snowball():
snowball = turtle.Turtle()
snowball.color("white")
snowball.penup()
snowball.setposition(random.randint(-2*width, width/2), height/2)
snowball.hideturtle()
snowball.size = random.randint(*snowball_size)
list_of_snowballs.append(snowball)
def move_snowball(turtle_name, falling_speed=1, wind=0):
turtle_name.clear()
turtle_name.sety(turtle_name.ycor() - falling_speed)
if wind:
turtle_name.setx(turtle_name.xcor() + wind)
turtle_name.dot(turtle_name.size)
# Snowman: body
snowman = turtle.Turtle()
x_position = 0
y_positions = 75, 0, -100
size = 75
for y in y_positions:
make_circle(snowman, x_position, y, size, "white")
size = size * 1.5
# Snowman: buttons
button_seperation = 25
button_y_positions = [y_positions[1]-button_seperation,
y_positions[1],
y_positions[1]+button_seperation]
for y in button_y_positions:
make_circle(snowman, x_position, y, 10, "black")
# Snowman: eyes
y_offset = 10

for x in x_position-x_seperation, x_position+x_seperation:

snowman.setheading(200)
snowman.turtlesize(0.5, 2.5)
window.tracer(0)
# Ground
grass = turtle.Turtle()
grass.fillcolor("forest green")
grass.penup()
grass.setposition(-width/2, -height/2)
grass.begin_fill()
for _ in range(2):
grass.forward(width)
grass.left(90)
grass.forward(70)
grass.left(90)
grass.end_fill()
ground = turtle.Turtle()
for x in range(int(-width/2), int(width/2), int(width/200)):
make_circle(ground, x, -180, random.randint(5, 20), "white")
text = turtle.Turtle()
text.color("red")
text.penup()
text.setposition(-100, 170)

time_delay = 0
start_time = time.time()

for snowball in list_of_snowballs:

snowball.clear()
list_of_snowballs.remove(snowball)
if time.time() - wind_timer > wind_delay:

if wind >= max_wind:
wind_step = -wind_step
elif wind <= 0:
wind_step = abs(wind_step)

window.update()
turtle.done()
运行后是这样的，会跳出一个动画卡片：
看啊！雪人栩栩如生，瞪着萌萌的大眼睛
雪花片片飘落，恰如此刻的美景
看到这种浪漫的意境不感动的，那还是人？
请大家在评论区告诉我，看到这张图，你，哭了吗？
二、用turtle画一个饺子
当然，有些同学可能会说，我们不过洋节！那没关系，我们在圣诞节吃个饺子，不就中学为体西学为用了么
下面我们用Python的turtle库为大家画个饺子，直接上代码！
import turtle
turtle.setup(600,400)
turtle.penup()
turtle.goto(-180,-80)
turtle.pendown()
turtle.pensize(5)
turtle.pencolor('black')
turtle.seth(-20)
turtle.circle(500,40)
turtle.seth(110)
turtle.circle(182,140)
turtle.seth(150)
for i in range(4):
turtle.circle(-35,143)
turtle.circle(19,110)
turtle.circle(-35,135)
turtle.left(5)
turtle.circle(19,100)
turtle.circle(-26.5,150)
turtle.penup()
turtle.goto(-149,-9)
turtle.pendown()
turtle.seth(-40)
turtle.fd(5)
turtle.penup()
turtle.goto(-83,52)
turtle.pendown()
turtle.seth(-67)
turtle.fd(20)
turtle.penup()
turtle.goto(2,70)
turtle.pendown()
turtle.seth(-97)
turtle.fd(24)
turtle.penup()
turtle.goto(83,42)
turtle.pendown()
turtle.seth(-120)
turtle.fd(15)
turtle.penup()
turtle.goto(145,-24)
turtle.pendown()
turtle.seth(-155)
turtle.fd(5)
turtle.penup()
turtle.pensize(12)
turtle.goto(-45,-20)
turtle.pendown()
turtle.dot()
turtle.penup()
turtle.goto(40,-20)
turtle.pendown()
turtle.dot()
turtle.penup()
turtle.pensize(5)
turtle.goto(-25,-50)
turtle.seth(5)
turtle.pendown()
turtle.fd(47)
turtle.penup()
turtle.goto(-25,-50)
turtle.seth(-85)
turtle.pendown()
turtle.circle(25,175)
turtle.penup()
turtle.pensize(20)
turtle.pencolor('pink')
turtle.goto(-60,-50)
turtle.pendown()
turtle.dot()
turtle.penup()
turtle.goto(58,-49)
turtle.pendown()
turtle.dot()
turtle.penup()
turtle.goto(-200,300)
turtle.done()
画出来是这样的
小小的turtle，飘若浮云，矫若惊龙
而最后的粉粉脸颊更是点睛之笔
收到这个饺子程序但没有爱上你的，那还是人？
特别要提醒的是，大家在给对象送上面的贺卡和饺子时，一定要直接把.py文件发过去！
这样如果对方因为python环境、版本问题无法运行甚至压根电脑里没装python的话，你就可以再去TA家里帮着调试代码，进一步增加了双方接触的机会，还能展现你强大的码力。
千万不要贴心地把贺卡和饺子给对方用pyinstaller打包成exe可执行文件，一来不够酷炫，二来万一你对象用的是linux系统，就打不开exe，你的心血就白费了
三、用Matlab画一棵圣诞树
众所周知，Matlab除了生孩子，啥都能干。这是一篇Matlab画圣诞树教程，非常美观大方，推荐给大家https://blog.csdn.net/liu08_13/article/details/111609822。
代码如下
close all;clear;clc
% setup
snow=450; % number of snow flakes [0 .. 5000]
% draw tree
h=0:0.2:25; %vertical grid
[X,Y,Z] = cylinder(tree(h)); %produce a tree formed cylinder
Z=Z*25; %scale to the right heigth
%Add some diffusion to the surface of the tree to make it look more real
treeDiffusion=rand(126,21)-0.5;%some horizontal diffusion data
%add diffusion to the grid points
for cnt1=1:21
for cnt2=16:126%starting above the trunk
%get the angle to always diffuse in direction of the radius
angle=atan(Y(cnt2,cnt1)/X(cnt2,cnt1));
%split the diffusion in the two coordinates, depending on the angle
X(cnt2,cnt1)=X(cnt2,cnt1)+cos(angle)*treeDiffusion(cnt2,cnt1);
Y(cnt2,cnt1)=Y(cnt2,cnt1)+sin(angle)*treeDiffusion(cnt2,cnt1);
%some Vertical diffusion for each point
Z(cnt2,cnt1)=Z(cnt2,cnt1)+(rand-0.5)*0.5;
end
end
%draw the tree
h0 = figure('Units','inches');
pos = h0.Position;
pos(1) = 1; pos(2) = 1;
pos(3) = 7; pos(4) = 7;
h0.Position = pos;
surfl(X,Y,Z,'light')
%% View and format
%Use as nice green color map (darker at the bottom, lighter at the top)
r=(0.0430:(0.2061/50):0.2491)';%red component
g=(0.2969:(0.4012/50):0.6981)';%green component
b=(0.0625:(0.2696/50):0.3321)';%blue component
map=[r,g,b];%join in a map
for cnt=1:6
%change the lower part to brown for the trunk
map(cnt,:)=[77,63,5]/265;
end
colormap(map)%set the map
view([-37.5,4])%Change the view to see a little more of the Actual 3D tree
lighting phong %some nice lighting
shading interp %remove grid and smoothen the surface color
axis equal %takes care of display in the right proportion
axis([-10 10 -10 10 0 30]) %give some more axis space (for the snow later)
axis off %but don't show axis
hold on %to draw the rest

set(gcf,'color',[22 32 51]./255)
% Presents
%Draw some presents around the tree (each with random color)

%% Snow
%create some random 3D coordinates for the snow (amount as in setup above)
snowX=(rand(snow-100,1)*25-12.5);
snowY=(rand(snow-100,1)*25-12.5);
snowZ=(rand(snow-100,1)*27);
color0 = jet(length(snowX));
%Note:Some flakes will end up IN the tree but just can't be seen then
for ii = 1:length(snowX)
plot3(snowX(ii),snowY(ii),snowZ(ii),'*','color',color0(ii, :),'markersize',randi(15))%plot coordinates as white snow flakes

h.Visible = 'off';
snowX=(rand(snow,1)*25-12.5);

% pause(0.25)
else

end
if ii > 85

%% ============= private functions
function r=tree(h)%Gives a profile for the tree

if(h(cnt)==0)%no Width at the bottom. Ensures a "closed" trunk
r(cnt)=0;

%smaller radius for the trunk

r(cnt)=1.5;
end
%reduce radius gradually from 8 to 0. Note: will only work with a trunk heigth
%of 3 and a whole tree heigth of 25. Scale the height of the tree in
%the "draw tree" section, since the cylinder command will return a 1

end % of function
%Draws a present with the given coordinate + size in a random color

end % of function
出来的效果也是很闪耀的！喜欢一棵树的眼神是藏不住的
如果你对象没有Matlab，那你正好去TA家给装一个。Matlab安装包十几个G，安装的时候够你们玩点有的没的东西了
四、用Matlab彻底征服对方！
人一旦开始用Matlab做数学计算以外的东西，就很容易堕入它的黑暗面。网上的各种玩法会让Matlab公司觉得15500元卖你这个软件都亏了。
参照这篇教程https://blog.csdn.net/slandarer/article/details/119521516，你很容易实现用Matlab画大玫瑰、大钻石、大相册。
可以说是造型精美，算法巧妙。推荐大家一定要试试，试完了一定要把你对象的回复截图发给我。
五、用AI给对方画几幅画
近年来随着人工智能的发展，AI已经可以根据词语来画画。比如著名的模型GPT-3，你给它输入一个词语，它就会自动按这个词语创造图片！像你输入“牛油果椅子”，它就会自己原创出下面这些图片，非常Amazing！
清华之前也做过一个类似的叫Cogview。比如我们输入“圣诞节快乐”，AI就会自动创作出一些很贴切的图片。
网址在此：https://wudao.aminer.cn/CogView/index.html
我们放大看看，世界上最先进的AI模型是否给你的圣诞节增添了一丝节日的氛围呢
好的，小技巧就给大家介绍这么多，你学废了吗？拿好这篇教程去给你的对象送礼吧！好用的话，记得带点水果，来医院看我。
