FileNotFoundError: [Errno 2] No such file or directory

Hi I want to use Python to delete the specific tag in a xml file.
Here is for example what I want to delete: <edge id="-28029380" from="444363583" to="307773297" priority="21" type="railway.highspeed" spreadType="center" shape="30808.38,22280.38 30815.34,22079.71 30818.81,21993.54 30825.20,21825.23 30834.10,21591.29 30834.28,21586.33" bidi="28029380" distance="58689.58"> <lane id="-28029380_0" index="0" allow="rail_fast" speed="55.56" length="691.54" shape="30808.43,22278.88 30815.34,22079.71 30818.81,21993.54 30825.20,21825.23 30834.10,21591.29 30834.23,21587.82"/> </edge>
and here is the python code:
`#！usr/bin/python

-- coding: utf-8 --

import xml.etree.ElementTree as ET
tree = ET.parse(r'C:\Users\zzj\Desktop\test\test.xml')
root = tree.getroot()
animNode = root.find('edge')
if animNode.attrib['type'] == 'railway.highspeed':
root.remove(animNode)
tree.write(r'C:\Users\zzj\Desktop\test\finish.xml')`

then I get the error of FileNotFoundError: [Errno 2] No such file or directory. I tried many time but the path doesn't work, could somebody help?
many thanks!
