how to edit xml root attributes with python-CodePudding

Recently ive been messing around with editing xml files with a python script for a project im working on but i cant figure out how to edit the attributes of the root element.

for example the xml file would say:

<root width="200">
  <element1>
  </element1>
</root>

what i want to do is have my code find the width attribute and change it to some other value, i know how to edit elements after the root but not the root itself

code im using for changing attributes

You could use the following module xml.etree.ElementTree. With this module you can set up attributes using xml.etree.ElementTree.Element.set() Here is an example of snippet you could use:

import xml.etree.ElementTree as ET

tree = ET.parse('input.xml')
root = tree.getroot()
root.set('width','400')
print(root.attrib)

tree.write('output.xml')
