如何计算python 3中两个矩形中心之间的中心？

def calculate_center(rect1, rect2):
    x1, y1 = rect1['center']
    x2, y2 = rect2['center']
    
    distance_x = abs(x2 - x1)
    distance_y = abs(y2 - y1)
    
    center_x = (x1 + x2) / 2
    center_y = (y1 + y2) / 2
    
    return center_x, center_y

# 示例矩形数据
rect1 = {'center': (1, 2)}
rect2 = {'center': (3, 4)}

# 计算中心坐标
center_x, center_y = calculate_center(rect1, rect2)
print("两个矩形中心之间的中心坐标为：({}, {})".format(center_x, center_y))
