ET 是 ElementTree 库的别名或者是导入的模块，使用 ET.Element('annotation') 创建了一个名为 annotation 的元素，它代表了这个XML文档的根节点。
Element() 方法会返回一个 Element 类型的对象，该对象代表了一个XML元素。
这个XML文档的根节点是 annotation，它是这个XML文档的最上层元素，它可以包含其它元素或者属性，而其它元素或者属性都是它的子元素或者子属性。
你可以通过在这个根元素上调用方法，如 .append() 或 .attrib，来添加子元素或者属性。

使用 ElementTree 库创建一个 XML 文档中的 size 元素，并在其中添加 width 和 height 子元素，
然后将它们的文本内容设置为图像 block_image 的宽度和高度，最终生成以下 XML 结构：
<size>
<width>图像宽度</width>
<height>图像高度</height>

最后将size 元素 添加到根节点 block_root = ET.Element('annotation') 中

使用了 ElementTree 库中的 findall() 方法和 find() 方法来查找 XML 元素中的特定子元素，并将其文本内容转换为 Python 中的数据类型。
for obj in root.findall('object'): 找到该 XML 元素中所有名为 object 的子元素，并对每一个 object 子元素执行下面的代码。
在循环内部，obj.find('name').text 获取了当前 object 子元素下的名为 name 的子元素，并返回该子元素的文本内容，这里是一个字符串类型，赋值给了 name 变量。

这段代码使用 Python 中的 ElementTree 模块创建了一个名为 "tree" 的 XML 文档对象，并将其初始化为 "block_root" 元素的根节点。
具体来说，这里的 ET 是 ElementTree 模块的别名，block_root 是一个 Element 对象，表示 XML 文档中的根元素。
ET.ElementTree(block_root) 将 Element 对象包装在 ElementTree 对象中，以便使用 ElementTree 模块提供的方法来处理 XML 文档。
通过将根元素传递给 ElementTree 构造函数，我们可以创建一个表示整个 XML 文档的对象，可以用于遍历、修改或序列化 XML 数据。
