CodePudding user response:

First in terms of your original code, is to write your slot_btn in TTP, want to receive the self must be clicked. Connect (slot_btn) send a self inside, this just python class foundation

 
BTN. Clicked. Connect (lambda: slot_btn (self))

Secondly pyqt5 written not so you have a look at the document again, I also have blog based on designer's introductory tutorial,
