python - 使用 Python 数据结构表示这一点的最佳方式

Question

  <specification> 
    <propertyName> string </propertyName>
    <value> 
      <number> 
        <value> anyNumberHere </value>
      </number>
      <text> 
        <value> anyTextHere </value>
      </text>
      <URL> 
        <value> anyURIHere </value>
      </URL>
    </value>
    <!-- ... 1 or more value nodes here ... -->
  </specification>
  <!-- ... 1 or more specification nodes here ... -->

我需要为 API 构建此请求，用户将在其中传递这些值。那么，最好的表示方式应该是什么，以便该方法的用户可以轻松地将相应的值传递给操作？

我在想:

字典列表:

[specification1, specification2, specification3]

地点:

specification1= [value1, value2]

地点:

value1 = {number:anyNumberHere, text:anyTextHere, URL:anyURIHere}
value2 = {number:anyNumberHere, text:anyTextHere, URL:anyURIHere}

但是，我无法容纳:<propertyName>这里。有什么建议吗？

此外，这听起来很复杂。我们可以像在 Java 中那样进行对象封装吗？我明白，我们可以，但我很好奇，python 中推荐的方式是什么？

My logic for now, suggestions (incorrect due to propertyName):
    #specification is a List of List of Dicts
    for spec in specification:
        specification_elem = etree.SubElement(root, "specification")
        propertyName_elem = etree.SubElement(specification_elem,"propertyName")
        propertyName_elem.text = spec_propertyName

        for value in spec:
            value_elem = etree.SubElement(specification_elem, "value")
            for key in value:
                key_elem = etree.SubElement(value_elem, key)
                keyValue_elem = etree.SubElement(key_elem, "value")
                keyValue_elem.text = value[key]

在这里，我将通过spec_propertyName ，作为差异参数。因此，用户将通过:specification and spec_propertyName

规范对象列表如何，每个对象都有一个 property_name 和一个 value 字典列表？ (values 可以是对象列表而不是字典。)

例如:

class Value(object):
    def __init__(self,
                 number=None,
                 text=None,
                 url=None):
        self.number = number
        self.text = text
        self.url = url

class Specification(object):
    def __init__(self, propertyName):
        self.propertyName = propertyName
        self.values = []

spec1 = Specification("Spec1")
spec1.values = [Value(number=3,
                      url="http://www.google.com"),
                Value(text="Hello, World!",
                      url="http://www.jasonfruit.com")]

spec2 = Specification("Spec2")
spec2.values = [Value(number=27,
                      text="I can haz cheezburger?",
                      url="http://stackoverflow.com"),
                Value(text="Running out of ideas.",
                      url="http://news.google.com")]
