Python如何构建xml文档

# 如何构建xml文档
from xml.etree.ElementTree import Element, ElementTree, tostring

e = Element('Data')
e.set('name', 'abc')
e.text = '123'

e2 = Element('Row')
e3 = Element('Open')
e3.text = '8.80'
e2.append(e3)
print(tostring(e2))
e.text = None
e.append(e2)
print(tostring(e))

et = ElementTree(e)
et.write('demo2.xml')

import csv

    return ElementTree(root)


et = csvToXml('test.csv')
et.write('test.xml')
