...and if you don't know beforehand if you have an uploaded file, try
something like:

from mod_python import apache, util
    
    def read(self, request):
        # Retrieve the submitted CGI parameters from Apache/mod_python.
        # ONLY CALL ONCE per request.
        newData = util.FieldStorage(request, 1).list
        self.requestParams.clear()
        if newData is not None:
            for eachParam in newData:
                name = self.unicode(eachParam.name)
                if eachParam.filename:
                    fileData = eachParam.file.read()
                    filename = self.unicode(eachParam.filename)
                    self.requestParams[name] = (filename, fileData)
                else:
                    value = self.unicode(eachParam.value)
                    self.requestParams[name] = value
