Python 使用重复标记读取XML

您可以使用

findall

方法获取作者的完整列表，循环遍历作者并从中生成单个字符串

for book in root.findall('book'):
    title = book.find('title').text
    author = book.find('author')
    year = book.find('year').text
    price = book.find('price').text
    # print(title,author,year,price)

    ...:     author = ', '.join([auth.text for auth in book.findall('author')]) 
    ...:     year = book.find('year').text 
    ...:     price = book.find('price').text
