方法一:使用matplotlib和numpy库

```python

import matplotlib.pyplot as plt

import numpy as np

def rose_curve(theta, k):

r = np.cos(k * theta)

return r

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')

plt.axis('equal')

plt.title('A Rose in Python')

plt.show()

```

方法二:使用turtle库

```python

import turtle

def draw_flower():

turtle.bgcolor("black")

turtle.pensize(2)

colors = ["red", "blue", "purple", "yellow", "orange"]

for i in range(36):

turtle.color(colors[i % 5])

turtle.forward(100)

turtle.left(45)

turtle.forward(100)

turtle.left(135)

turtle.forward(100)

turtle.left(45)

turtle.forward(100)

turtle.left(170)

turtle.hideturtle()

turtle.done()

draw_flower()

```

方法三:使用C语言

```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("
