中式花格是一个由随机长方形，正方形，圆形组成的图案，请用python程序编写一个中式花格图案。

好的，我可以使用Python中的turtle模块来绘制中式花格图案。以下是示例代码：

import turtle
import random

# 随机生成长方形、正方形、圆形
def draw_shape(length, shape):
    turtle.pendown()
    turtle.color('black', 'white')
    turtle.begin_fill()
    if shape == 'rectangle':
        turtle.forward(length)
        turtle.right(90)
        turtle.forward(length/2)
        turtle.right(90)
        turtle.forward(length)
        turtle.right(90)
        turtle.forward(length/2)
    elif shape == 'square':
        turtle.forward(length)
        turtle.right(90)
        turtle.forward(length)
        turtle.right(90)
        turtle.forward(length)
        turtle.right(90)
        turtle.forward(length)
    elif shape == 'circle':
        turtle.circle(length/2)
    turtle.end_fill()
    turtle.penup()

# 绘制中式花格图案
def draw_pattern(width, height):
    turtle.speed(0)
    turtle.hideturtle()
    turtle.penup()
    turtle.setpos(-width/2, -height/2)

    shapes = ['rectangle', 'square', 'circle']
    for x in range(0, width, 50):
        for y in range(0, height, 50):
            shape = random.choice(shapes)
            draw_shape(50, shape)
            turtle.setpos(-width/2 + x, -height/2 + y)

    turtle.done()
    
# 调用函数绘制中式花格图案
draw_pattern(500, 500)

该程序使用turtle模块绘制随机生成的长方形、正方形、圆形来组成中式花格图案。运行后，程序将生成一个500x500的中式花格图案。
