使用pillow库生成一个彩色棋盘

Sure, here is some sample code to generate a colored chessboard using the Pillow library in Python:

from PIL import Image

# Define image size and block size
size = 400
block_size = size//8

# Create image object
img = Image.new('RGB', (size, size), (255, 255, 255))

# Create color tuples for white and black
white = (255, 255, 255)
black = (0, 0, 0)

# Fill the image with alternating white and black blocks
for i in range(8):
    for j in range(8):
        if (i+j) % 2 == 0:
            color = white
        else:
            color = black
        img.paste(color, (i*block_size, j*block_size, (i+1)*block_size, (j+1)*block_size))

# Save the image
img.save('colored_chessboard.png')

Hope this helps!
