How to edit xml config file in python 3?

I have a xml config file and needs to update particular attribute value.

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <testCommnication>
          <connection intervalInSeconds="50" versionUpdates="15"/>
        </testCommnication>
</configuration>

I just need to update the "versionUpdates" value to "10".

How can i achieve this in python 3.

I have tried xml.etree and minidom and not able to achieve it.

Please use xml.etree.ElementTree to modify the xml:
Edit: If you want to retail the attribute order, use lxml instead. To install, use pip install lxml

# import xml.etree.ElementTree as ET
from lxml import etree as ET
tree = ET.parse('sample.xml')
root = tree.getroot()

# modifying an attribute
for elem in root.iter('connection'):
    elem.set('versionUpdates', '10')

tree.write('modified.xml')   # you can write 'sample.xml' as well

Content now in modified.xml:

<configuration>
    <testCommnication>
          <connection intervalInSeconds="50" versionUpdates="10" />
        </testCommnication>
</configuration>

You can use xml.etree.ElementTree in Python 3 to handle XML :

import xml.etree.ElementTree
config_file = xml.etree.ElementTree.parse('your_file.xml')
config_file.findall(".//connection")[0].set('versionUpdates', 10))
config_file.write('your_new_file.xml')
