API used successfully in Python 2.7 application does not work in Python 3.6

[dschreyergill]

I have an application written in python 2.7 that uses pysimplesoap successfully. I am in the process of migrating that app to Python 3.6, and have found that the pysimplesoap module is behaving differently in at least one case. Here is a SOAP request sent by the 2.7 application:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:tns="http://fprint.net/PAC">
<soapenv:Header/>
<soapenv:Body>
    <**tns:viewServer**>
        <username>L3cdnc</username><password>!@l3cndc714</password><ServerID>185216</ServerID>
    </**tns:viewServer**>
</soapenv:Body>
</soapenv:Envelope>

The next one is what is sent by the python 3 code:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:tns="http://fprint.net/PAC">\n
<soapenv:Header/>\n
<soapenv:Body>
    <**viewServer**>
        <username>L3cdnc</username><password>!@l3cndc714</password><ServerID>212788</ServerID>
    </**viewServer**>
</soapenv:Body>
</soapenv:Envelope>

The way the application uses pysimplesoap has not changed. The differences above are in bold. What is causing the ns to not be prepended to the viewServer tag in Python 3, and how can I get around it?

Thank you.
