Всем привет, я полный ноль в программировании и только изучаю язык Python. И изучать я решил сразу с практики, так как чтение книг для меня нудное задача. Решил для начала создать простое приложение в котором на главном окне есть кнопка и при нажатии на нее открывалась бы второе окно, а первое закрылось. В QtDesinger создал два окна и импортировал их в py файл. Далее создал файл test.py и импортировал туда классы из двух окон и по примерам с инета пробовал сделать действие при котором нажатие на кнопку открывал бы второе окно. Но выдает ошибку AttributeError: 'Ui_MainWindow' object has no attribute 'close'.
Код из test.py
Python: 
from PyQt5 import QtWidgets, QtGui,QtCore
from calk import Ui_MainWindow
from calk2 import Ui_Form
import sys

class mywindow(QtWidgets.QMainWindow):
    def __init__(self):
        super(mywindow, self).__init__()
        self.ui = Ui_MainWindow()
        self.ui.setupUi(self)

    def show_mywindow(self):
        self.ui.pushButton.clicked.connect(self.show_mywindow2)
        self.ui.pushButton.clicked.connect(self.ui.close)
        self.ui.show()

    def show_mywindow2(self):
        self.ui2 = mywindow2()
        self.ui2.show()


class mywindow2(QtWidgets.QMainWindow):
    def __init__(self):
        super(mywindow2, self).__init__()
        self.ui2 = Ui_Form()
        self.ui2.setupUi(self)



if __name__ == '__main__':
    app = QtWidgets.QApplication(sys.argv)
    w = mywindow()
    w.show()

    sys.exit(app.exec_())

Замените эти строки:
Python: 
def show_mywindow(self):
    self.ui.pushButton.clicked.connect(self.show_mywindow2)
    self.ui.pushButton.clicked.connect(self.ui.close)
    self.ui.show()
на такие
Python: 
def show_mywindow(self):
    self.ui.pushButton.clicked.connect(self.show_mywindow2)
    self.ui.pushButton.clicked.connect(self.close)
