将Python CSV数据转换为XML

import csv
import xml.etree.ElementTree as ET

csv_file = open('data.csv', 'r')
csv_reader = csv.DictReader(csv_file)

root = ET.Element('data')

for row in csv_reader:
    item = ET.SubElement(root, 'item')
    for key, value in row.items():
        sub_element = ET.SubElement(item, key)
        sub_element.text = value

xml_str = ET.tostring(root, encoding='utf-8').decode('utf-8')

xml_file = open('data.xml', 'w')
xml_file.write(xml_str)
xml_file.close()
