使用Python绘制玫瑰花

方法一:使用matplotlib和numpy库

```python

import matplotlib.pyplot as plt

import numpy as np

定义玫瑰曲线函数

def rose_curve(theta, k):

r = np.cos(k * theta)

return r

绘制函数

theta = np.linspace(0, 2 * np.pi, 1000)

k = 5

r = rose_curve(theta, k)

x = r * np.cos(theta)

y = r * np.sin(theta)

plt.figure(figsize=(6, 6))

plt.plot(x, y, 'r') 使用红色绘制玫瑰花

plt.axis('equal') 确保x轴和y轴的刻度相同

plt.title('A Rose in Python')

plt.show()

```

方法二:使用turtle库

```python

import turtle

设置画布和画笔

screen = turtle.Screen()

screen.bgcolor("white")

pen = turtle.Turtle()

pen.speed(5)

pen.pensize(2)

绘制花瓣形状

def draw_petal():

for _ in range(200):

pen.right(1)

pen.forward(1)

组合花瓣形成花朵

pen.color("red")

pen.begin_fill()

for _ in range(9):

draw_petal()

pen.left(40)

pen.end_fill()

turtle.done()

```

方法三:使用matplotlib创建3D玫瑰花

```python

import numpy as np

import matplotlib.pyplot as plt

from mpl_toolkits.mplot3d import Axes3D

定义玫瑰花的参数

k = 5

theta = np.linspace(0, 2 * np.pi, 100)

r = np.sin(k * theta)

转换为笛卡尔坐标

x = r * np.cos(theta)

y = r * np.sin(theta)

z = np.linspace(-1, 1, 100)

创建3D图形

fig = plt.figure()

ax = fig.add_subplot(111, projection='3d')

绘制玫瑰花

for z_val in z:

ax.plot(x, y, z_val, color='r', alpha=0.1) 使用透明度绘制多个花瓣

设置坐标轴标签

ax.set_xlabel('X轴')

ax.set_ylabel('Y轴')

ax.set_zlabel('Z轴')

ax.set_title('立体玫瑰花')

显示图形

plt.show()

```

使用C语言绘制玫瑰花

```c

include

int main() {

int i, j, n;

printf("请输入玫瑰花的大小(建议输入10-20之间的数):");

scanf("%d", &n);

for (i = -n / 2; i <= n / 2; i++) {

for (j = -n / 2; j <= n / 2; j++) {

if (i * i + j * j <= (n / 2) * (n / 2)) {

if ((i + j) % 2 == 0) {

printf(" ");

} else {

printf("
