使用Python3绘制心形,你可以选择多种方法,这里提供两种常见的方法:
方法一:使用Turtle Graphics
from turtle import *from time import sleepdef go_to(x, y):up()goto(x, y)down()def big_Circle(size):speed(1)for i in range(150):forward(size)right(0.3)def small_Circle(size):speed(1)for i in range(210):forward(size)right(0.786)def line(size):speed(1)forward(51 * size)def heart(x, y, size):go_to(x, y)left(150)begin_fill()line(size)big_Circle(size)small_Circle(size)left(120)small_Circle(size)big_Circle(size)line(size)end_fill()def arrow():pensize(10)setheading(0)go_to(-400, 0)left(15)forward(150)go_to(339, 178)forward(150)def arrowHead():pensize(1)speed(1)color('red')调用函数绘制心形heart(0, 0, 100)调用函数绘制箭头arrow()结束绘制done()
方法二:使用matplotlib和numpy
import matplotlib.pyplot as pltfrom mpl_toolkits.mplot3d import Axes3Dimport numpy as np生成爱心点x_lim = np.linspace(-10, 10, 150)y_lim = np.linspace(-10, 10, 150)z_lim = np.linspace(-10, 10, 150)X_points = []Y_points = []Z_points = []for x in x_lim:for y in y_lim:for z in z_lim:if (x2 + (9/4)*y2 + z2 - 1)3 - (9/80)*y2*z3 - x2*z3 <= 0:X_points.append(x)Y_points.append(y)Z_points.append(z)绘制爱心fig = plt.figure()ax = fig.add_subplot(111, projection='3d')ax.scatter(X_points, Y_points, Z_points, c='red')plt.show()
以上代码分别展示了如何使用Turtle Graphics和matplotlib库来绘制心形。你可以根据自己的喜好和需求选择合适的方法进行尝试。
