如何在Python3.5上使用ElementTree将csv转换为xml文件

import csv
import xml.etree.ElementTree as ET

csv_file = 'data.csv'  # CSV文件路径
xml_root = ET.Element('data')  # 创建XML根节点

with open(csv_file, 'r') as file:
    csv_data = csv.reader(file)
    headers = next(csv_data)  # 获取CSV文件的表头

    for row in csv_data:
        xml_row = ET.SubElement(xml_root, 'row')  # 创建XML行节点
        for i, value in enumerate(row):
            xml_field = ET.SubElement(xml_row, headers[i])  # 创建XML字段节点
            xml_field.text = value  # 设置字段节点的文本内容

xml_file = 'data.xml'  # XML文件路径

tree = ET.ElementTree(xml_root)
tree.write(xml_file, encoding='utf-8', xml_declaration=True)
