Python浪漫表白源码合集（爱心、玫瑰花、照片墙）

程序员也可以很浪漫！

1. 一行代码画爱心

print('\n'.join([''.join([('Love'[(x-y)%4]if((x*0.05)**2+(y*0.1)**2-1)**3-(x*0.05)**2*(y*0.1)**3<=0 else' ')for x in range(-30,30)])for y in range(15,-15,-1)]))

1. 用turtle库画一朵玫瑰花

#!/usr/bin/env python
# coding: utf-8

#绘制玫瑰花并添加文字
import turtle 
# 设置画布大小
# turtle.screensize(canvwidth=None, canvheight=None, bg=None)
turtle.setup(width=0.6, height=0.6)
# 设置初始位置
turtle.penup()
turtle.left(90)
turtle.fd(200)
turtle.pendown()
turtle.right(90)
 
# 输出文字
printer = turtle.Turtle()
printer.hideturtle()
printer.penup()
printer.back(200)
printer.write("赠给亲爱的 XX\n\n", align="right", font=("楷体", 16, "bold"))
printer.write("from XXX", align="center", font=("楷体", 12, "normal"))

可以把玫瑰花打包成exe文件，发送给没有安装Python的对象，在她/他的电脑上运行

2. 用turtle库画爱心加文字

import turtle
import random

def love(x, y):  # 在(x,y)处画爱心lalala
    lv = turtle.Turtle()
    lv.hideturtle()
    lv.up()
    lv.goto(x, y)  # 定位到(x,y)

    def curvemove():  # 画圆弧
        for i in range(20):
            lv.right(10)
            lv.forward(2)

    lv.color('red', 'pink')
    lv.speed(10000000)
    lv.pensize(1)
    # 开始画爱心lalala
    lv.down()
    lv.begin_fill()
    lv.left(140)
    lv.forward(22)
    curvemove()
    lv.left(120)
    curvemove()
    lv.forward(22)
    lv.write("YZ", font=("Arial", 12, "normal"), align="center")  # 写上表白的人的名字
    lv.left(140)  # 画完复位
    lv.end_fill()


def tree(branchLen, t):
    if branchLen > 5:  # 剩余树枝太少要结束递归
        if branchLen < 20:  # 如果树枝剩余长度较短则变绿
            t.color("green")
            t.pensize(random.uniform((branchLen + 5) / 4 - 2, (branchLen + 6) / 4 + 5))
            t.down()
            t.forward(branchLen)
            love(t.xcor(), t.ycor())  # 传输现在turtle的坐标
            t.up()
            t.backward(branchLen)
            t.color("brown")
            return
        t.pensize(random.uniform((branchLen + 5) / 4 - 2, (branchLen + 6) / 4 + 5))
        t.down()
        t.forward(branchLen)
        # 以下递归
        ang = random.uniform(15, 45)
        t.right(ang)
        tree(branchLen - random.uniform(12, 16), t)  # 随机决定减小长度
        t.left(2 * ang)
        tree(branchLen - random.uniform(12, 16), t)  # 随机决定减小长度
        t.right(ang)
        t.up()
        t.backward(branchLen)

myWin = turtle.Screen()
t = turtle.Turtle()
t.hideturtle()
t.speed(1000)
t.left(90)
t.up()
t.backward(200)
t.down()
t.color("brown")
t.pensize(32)
t.forward(60)
tree(100, t)
myWin.exitonclick()

照片墙

怀念香蜜夫妇，所以我用香蜜剧中的图生成了照片墙，放大看每一个小格都有一张照片。你也可以用情侣照生成回忆照片墙，送给喜欢的她/他。

#!/usr/bin/env python
# encoding: utf-8
from PIL import Image
import cv2
import os
os.chdir(r"F:\微信公众号\Python\30.520表白\代码\照片墙\new")
img = cv2.imread("start.jpg")      
height,width,channels = img.shape  
unit_size = 120                    
y_index = height//unit_size        
x_index = width//unit_size
new_img = Image.new('RGB',(width,height),'#FFFFFF')        
pic_list = []                     
for item in os.listdir("small_pictures"):
    if item.endswith(".jpg") or item.endswith(".JPG") : 
        pic_list.append(item)       
total = len(pic_list)  
x=0
y=0
for i in range(x_index*y_index):
    print(f"目前进度{i}/{x_index*y_index}")     
    test = Image.open("small_pictures/" + pic_list[i%total]).resize((unit_size,unit_size), Image.ANTIALIAS)  
    new_img.paste(test,(x*unit_size,y*unit_size))  
    x+=1
    if x==x_index:
        x=0
        y+=1
print("素材图合成完毕！")
new_img.save("out.jpg",quality=100)  
src1 = cv2.imread("start.jpg")      
src2 = cv2.imread("out.jpg")        
result = cv2.addWeighted(src1,0.7,src2,0.3,0) 
cv2.imwrite("result.jpg",result)
