python爱心源代码集锦（18款）

以下是18款Python爱心的源代码示例，涵盖不同的打印形式和复杂度。

1. 基本的心形:

print("".join(["I love you\n".center(50, "*") for _ in range(5)]))

2. 旋转的心形:

import math
 
def f(x, y, z):
    return (1 - math.sqrt(x * x + y * y) / z) * 2
 
def heart(x, y, z, a):
    result = f(x, y, z)
    return a if result > 1 else 0 if result < 0 else result
 
def render(f, width, height, scale):
    output = []
    for y in range(height):
        row = []
        for x in range(width):
            row.append(heart(scale * (x - width // 2), scale * (y - height // 2), scale, 0.08) * 3)
        output.append("".join("#"[:int(256 * min(1, i) ** 0.75)] for i in row))
    print("\n".join(output))
 
render(heart, 80, 20, 10)

3. 使用ASCII艺术的心形:

# https://www.ascii-art.de/ascii/h/heart.txt
print("""
    /$$$$$$  /$$$$$$$
   /$$$$$$$ /$$_____/
  /$$_____/ | $$$$$$
 /$$$$$$$/  |______/
|_______/
""")

4. 使用图形库(如Turtle)绘制形状:

import turtle
 
def draw_heart(t, x, y):
    t.up()
    t.goto(x, y)
    t.down()
    t.begin_fill()
    t.color("red", "pink")
    t.left(140)
    t.forward(22)
    t.right(140)
    t.forward(22)
    t.left(120)
    t.forward(22)
    t.right(120)
    t.forward(22)
    t.end_fill()
 
t = turtle.Turtle()
draw_heart(t, 0, 0)
turtle.done()

5. 使用Emoji表情作为爱心:

print("""
\u2764\uFE0F \u{1F31C} \u2764\uFE0F
\u2764\uFE0F \u{1F494} \u2764\uFE0F
""")

6. 使用Unicode字符打印爱心:

print('\u2764\uFE0F')

7. 使用字母打印爱心:

print("".join(["I love you\n".center(50, "*") for _ in range(5)]))

8. 使用图像库(如PIL)处理图片:

from PIL import Image, ImageDraw, ImageFont
 
width, height = 500, 500
image = Image.new('RGB', (width, height), 'white')
draw = ImageDraw.Draw(image)
font = ImageFont.truetype("arial.ttf", 25)
draw.text((100, 100), "I love you", font=font, fill="red")
image.show()

9. 使用matplotlib绘制图形:

import numpy as np
import matplotlib.pyplot as plt
 
theta = np.linspace(0, 2 * np.pi, 1000)
x = 16 * np.sin(theta)**3
y = 13 * np.cos(theta) - 5 * np.cos(2
