How to use the tomcatmanager.status_codes.values function in tomcatmanager

def response(self, response: requests.models.Response):
        self._response = response
        # parse the text to get the status code and results
        if response.text:
            lines = response.text.splitlines()
            # get the status line, if the request completed OK
            if response.status_code == requests.codes.ok:
                try:
                    statusline = response.text.splitlines()[0]
                    code = statusline.split(' ', 1)[0]
                    if code in tm.status_codes.values():
                        self.status_code = code
                        self.status_message = statusline.split(' ', 1)[1][2:]
                        if len(lines) > 1:
                            self.result = "\n".join(lines[1:])
                    else:
                        self.status_code = tm.status_codes.notfound
                        self.status_message = 'Tomcat Manager not found'
                except IndexError:
                    pass
