如何在python枕头上画条纹？

import numpy as np
import matplotlib.pyplot as plt

# 创建一个具有条纹模式的数组
width = 300
height = 200
stripes = np.zeros((height, width))
for i in range(height):
    for j in range(width):
        if j % 20 < 10:  # 每20个像素的一组，前10个像素设为1
            stripes[i, j] = 1

# 绘制条纹图案
plt.imshow(stripes, cmap='gray')
plt.axis('off')  # 隐藏坐标轴
plt.show()
