The above is unneeded if you use comtypes as below (and is unneeded
when using pythoncom, as well).

You don't intantiate the interface, you have to instantiate the COM object.
Something like
CreateObject("XCOM_Class")
but of course you have to use the correct argument in the call - the progid
of the COM object.
Alternatively you can use the CoClass from the typelibrary, look into the
generated module in the comtypes\gen directory for a class derived from
comtypes.CoClass.
InternetExplorer, for example, can be started in these ways:
# using the progid:
ie = CreateObject("InternetExplorer.Application")
# using the clsid:
ie = CreateObject("{0002DF01-0000-0000-C000-000000000046}")
# using the coclass from the generated module:
mod = GetModule("shdocvw.dll")
ie = CreateObject(mod.InternetExplorer)
