but this outputs

来自http://lxml.de/tutorial.html#serialisation
>>> root = etree.XML('<root><a><b/></a></root>')
>>> etree.tostring(root)
b'<root><a><b/></a></root>'
>>> print(etree.tostring(root, xml_declaration=True))
<?xml version='1.0' encoding='ASCII'?>
<root><a><b/></a></root>
>>> print(etree.tostring(root, encoding='iso-8859-1'))
<?xml version='1.0' encoding='iso-8859-1'?>
<root><a><b/></a></root>
>>> print(etree.tostring(root, pretty_print=True))
<root>
<a>
<b/>
</a>
</root>
