A.py
class GET_SYSTEM:
def __init__(self):
self.system_name = '123'
class GET_BOARD:
def __init__(self):
self.board_info = 'asd'
B.py
from A import GET_SYSTEM, GET_BOARD,
class A(GET_SYSTEM, GET_BOARD):
def get(self):
system_name = self.system_name
board_info = self.board_info
请问在B.py中怎么获取A中的 self.system_name 和 self.board_info
