python编程利用十种不同方法绘制心形线图像

以下是十种不同方法绘制心形线图像的Python代码：

方法一：使用matplotlib库绘制心形线图像

import numpy as np
import matplotlib.pyplot as plt

t = np.linspace(0, 2*np.pi, 1000)
x = 16 * np.sin(t)**3
y = 13 * np.cos(t) - 5 * np.cos(2*t) - 2 * np.cos(3*t) - np.cos(4*t)
plt.plot(x, y)
plt.axis('equal')
plt.show()

方法二：使用turtle库绘制心形线图像

import turtle

turtle.speed(0)
turtle.penup()
turtle.goto(-200,0)
turtle.pendown()

for i in range(200):
    turtle.right(1)
    turtle.forward(2)

turtle.left(140)

for i in range(200):
    turtle.right(1)
    turtle.forward(2)

turtle.penup()
turtle.goto(0, 100)
turtle.pendown()

turtle.circle(50)

turtle.done()

方法三：使用pygame库绘制心形线图像

import pygame
import math

pygame.init()
screen = pygame.display.set_mode((400, 400))
pygame.display.set_caption("Heart Curve")
font = pygame.font.Font(None, 30)
text = font.render("Heart Curve", True, (255, 0, 0))

while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            sys.exit()

    screen.fill((255, 255, 255))
    screen.blit(text, (150, 10))

    for x in range(0, 360):
        y = math.sin(math.radians(x)) * math.sqrt(abs(math.cos(math.radians(x)))) * 50
        pygame.draw.circle(screen, (255, 0, 0), (int(x) + 150, int(y) + 200), 1)

    pygame.display.flip()

方法四：使用numpy和matplotlib库绘制心形线图像

import numpy as np
import matplotlib.pyplot as plt

t = np.linspace(0, 2 * np.pi, 1000)
x = 16 * np.sin(t) ** 3
y = 13 * np.cos(t) - 5 * np.cos(2 * t) - 2 * np.cos(3 * t) - np.cos(4 * t)

fig, ax = plt.subplots()
ax.plot(x, y, 'r')
ax.set_aspect(1)
plt.show()

方法五：使用math库绘制心形线图像

import math
import turtle

turtle.speed(0)

for i in range(0, 360):
    t = math.radians(i)
    x = 16 * math.sin(t) ** 3
    y = 13 * math.cos(t) - 5 * math.cos(2 * t) - 2 * math.cos(3 * t) - math.cos(4 * t)
    turtle.goto(x * 10, y * 10)

turtle.done()

方法六：使用matplotlib和numpy库绘制心形线图像

import matplotlib.pyplot as plt
import numpy as np

t = np.linspace(0, 2 * np.pi, 1000)
x = np.sin(t) * np.sin(t) * np.sin(t)
y = np.cos(t) - np.cos(t) * np.cos(t) * np.cos(t)

fig, ax = plt.subplots()
ax.plot(x, y, 'r')
ax.set_aspect(1)
plt.show()

方法七：使用turtle库绘制心形线图像

import turtle

turtle.speed(0)

for i in range(0, 360):
    t = i / 180 * 3.1415926
    x = 16 * math.sin(t) ** 3
    y = 13 * math.cos(t) - 5 * math.cos(2 * t) - 2 * math.cos(3 * t) - math.cos(4 * t)
    turtle.goto(x * 10, y * 10)

turtle.done()

方法八：使用pygame库绘制心形线图像

import pygame
import math

pygame.init()

screen = pygame.display.set_mode((500, 500))

pygame.display.set_caption("Heart Curve")

font = pygame.font.Font(None, 25)
text = font.render("Heart Curve", True, (255, 0, 0))

while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            sys.exit()

    screen.fill((255, 255, 255))
    screen.blit(text, (190, 10))

    for i in range(0, 360):
        t = i / 180 * 3.1415926
        x = 16 * math.sin(t) ** 3
        y = 13 * math.cos(t) - 5 * math.cos(2 * t) - 2 * math.cos(3 * t) - math.cos(4 * t)
        pygame.draw.circle(screen, (255, 0, 0), (int(x) + 250, int(y) + 250), 2)

    pygame.display.update()

方法九：使用turtle库绘制心形线图像

import turtle

turtle.speed(0)

for i in range(0, 360):
    t = i / 180 * 3.1415926
    x = 16 * math.sin(t) ** 3
    y = 13 * math.cos(t) - 5 * math.cos(2 * t) - 2 * math.cos(3 * t) - math.cos(4 * t)
    turtle.goto(x * 10, y * 10)

turtle.done()
