You can use an extra variable, here i, to print lables.
Also, I removed end parameter so that it print line by line. In addition, I used f-string for printing format. For more detail, please see https://realpython.com/python-f-strings/

您可以使用额外的变量（此处为
i）来打印标签。另外，我删除了
end参数，以便它逐行打印。另外，我使用f-string作为打印格式。有关更多详细信息，请参阅 https://realpython.com/python-f-strings/You can use an extra variable, here
