Dear Arfan: I'm following with utmost interest this video of yours. It's very well explained and I'll study it from beginning till the end. Then I'll applicate it to my plans. Thank you and have a good day, Alberto.
Hello Arfan: I've copied the first part of this video, till 11:40 and get no error. But when i execute it with Python.exe I get an error ""Could not find QPushButton in PyQt5". Searching in the web I find that it is the effect of trying to execute with PyQt5 an application made with PyQt4. I don't know how it could be since everything is made with the same PyQt. On the web is said that to fix it write "btn = QTWidgets.QPusButton('Button')" but I get an error. I don't know if I should previously define this "btn" as a variable. Which is your advice to fix the problem of QPushButton? Thank you very much, Alberto,.
Hi Alberto,
I hope you are doing well.

In this exercisee on line 34 on "self.add_button.clicked.connect(sef.addStudent)" I get always the error: Attribute error: 'MainWindow' has no attribute 'addStudent'. If I change this word for another i get the same message. It is the only error that I get in this exercise and I have copied exactly your code. Thanks.
Of course I write "self.addStudent", not sef
