Answer 1

Why not just use f string?

password = 'secret'
user = 'jack'
host = '12.56.78.123'
xml = f'''<sut>
    <Cdu>
        <class>XXX</class>
        <conn>
            <class>XXX</class>
            <cli>
                <password>{password}</password>
                <user>{user}</user>
                <host>{host}</host>
                <connectOnInit>false</connectOnInit>
            </cli>
        </conn>
        <basic>
            <class>XXX</class>
        </basic>
    </Cdu>'''
print(xml)

output

<sut>
    <Cdu>
        <class>XXX</class>
        <conn>
            <class>XXX</class>
            <cli>
                <password>secret</password>
                <user>jack</user>
                <host>12.56.78.123</host>
                <connectOnInit>false</connectOnInit>
            </cli>
        </conn>
        <basic>
            <class>XXX</class>
        </basic>
    </Cdu>
