import sys
from PyQt5 import QtCore,QtGui,QtWidgets
from untitled import *

class My(QtWidgets.QMainWindow,Ui):
def init(self):
super(My, self).init()
self.setupUi(self)
self.setupUi2(self)

def login(self):
    pass

def reg(self):
    pass

if name == 'main':
app = QtWidgets.QApplication(sys.argv)
m = My()
m.show()
sys.exit(app.exec())

不过做到的逻辑和业务分离
也算是用上了信号和槽
