编写程序实现绘制三角形、正方形、五边形、六边形以及圆，并填充不同的颜色，程序也为图形添加文 本标题

编写一个简单的图形绘制程序，可以使用各种编程语言如Python的turtle模块或者Java的Graphics API。以下是使用Python turtle模块的一个基本示例：

import turtle

# 创建画笔对象
window = turtle.Screen()
pen = turtle.Turtle()

# 定义函数绘制形状并填色
def draw_shape(shape, color):
    pen.fillcolor(color)
    pen.begin_fill()
    if shape == 'triangle':
        for _ in range(3):
            pen.forward(100)
            pen.left(120)
    elif shape == 'square':
        for _ in range(4):
            pen.forward(100)
            pen.right(90)
    elif shape == 'pentagon':
        angle = 360 / 5
        for _ in range(5):
            pen.forward(100)
            pen.left(angle)
    elif shape == 'hexagon':
        angle = 360 / 6
        for _ in range(6):
            pen.forward(100)
            pen.left(angle)
    else:  # 圆
        pen.circle(50)
    pen.end_fill()

# 绘制图形及其标题
shapes = ['triangle', 'square', 'pentagon', 'hexagon', 'circle']
colors = ['red', 'blue', 'green', 'yellow', 'purple']

for i in range(len(shapes)):
    draw_shape(shapes[i], colors[i])
    pen.penup()  # 提起画笔
    pen.goto(i * 200, -200)  # 移动到新位置
    pen.pendown()  # 放下画笔
    pen.write(f"{shapes[i]} ({colors[i]})", align="center", font=("Arial", 18, "bold"))

# 关闭窗口
window.exitonclick()
