在循环中更改形状后，立即更新每个形状的填充颜色

# 创建一个包含多个形状的数组
shapes = [
    {'points': [(0, 0), (1, 0), (1, 1), (0, 1)], 'fill_color': 'red'},
    {'points': [(2, 2), (3, 2), (3, 3), (2, 3)], 'fill_color': 'blue'},
    {'points': [(4, 4), (5, 4), (5, 5), (4, 5)], 'fill_color': 'green'}
]

# 遍历每个形状
for shape in shapes:
    # 根据填充颜色逻辑进行更改
    if some_condition:
        shape['fill_color'] = 'yellow'
    else:
        shape['fill_color'] = 'purple'
    
    # 在界面上重新绘制或渲染形状
    draw_shape(shape)

# draw_shape函数用于绘制形状，具体实现可以根据项目需求进行定义
def draw_shape(shape):
    # 绘制形状的逻辑
    # 使用shape['fill_color']来填充形状的颜色
    ...
