问题 from xml.etree.ElementTree import ElementTree, Element, SubElement, dump elem = Element('1') sub = SubElement(elem, '2') tree = ElementTree(elem) dump(tree) dump(elem) In the code above, dumping tree (which is an ElementTree) and dumping elem (which is an Element) results in the same thing. Therefore I am having trouble determining what the difference is between the two. 回答1: dumping tree (which is an ElementTree) and dumping elem (which is an Element) results in the same thing. dump()
