파이썬 - 자기 자신을 다른 함수에 넘겨주기

Question

나는 AccountPopup (Popup)이라는 클래스를 가지고있다 :
나는 AccountPopup 클래스의 state_id_text 변수를 정의한다. 나는 .kv 파일에서 self.state_id_text.text 값을 얻는다. 이 함수의 값

def populate_tree_view_account_city(tree_view, parent, node):

당신은 기능과 액세스 그것에 클래스 'AccountPopup inside the function populate_tree_view_account_city , pass an object of the class 'AccountPopup의 데이터 멤버 state_id_text에 액세스하십시오. 새 인스턴스가 만들어 질 때마다 populate_tree_view_account_city 함수 안에 클래스의 새 인스턴스를 만들고 state_id_text을 초기화하려면 AccountPopup 내에 __init__ 메서드를 사용합니다.
