None이 아니라 Client()가 할당 되어야 된다고 생각하고 if self.btn_submit_pwd.rect.collidepoint(event.pos): if self.btn_input_pwd.text is not &#34;&#34;: pwd &#61; self.btn_input_pwd.text name &#61; self.btn_input_name.text self.data['pwd'] &#61; pwd self.data['name'] &#61; name json_data &#61; json.dumps(self.data) self.client.send_data(json_data.encode())btn_submit_pwd를 누르면 Client의 send_data함수를 실행시켜 Server에 데이터를 보내는 로직을 작성했습니다근데 작동시켜보면 self.client에 Client가 아닌 None이 계속해서 할당 되있어서 send_data함수를 실행시키지 못합니다 ㅠ제 생각엔 멀티쓰레드에서 self.client를 Client()로 할당하고 MultiSettingPage의 self.client 는 그냥 계속 None인 거 같은데,만약 제 생각이 맞다면 Client를 서로 공유하는 해결 방법이 있을까요?
