How to make clicking a keyboard button have a subsequent action? PyQt6/PySide6

Question

I'm trying to implement into my code the ability for the program to recognize if the user presses buttons on the keyboard, but I haven't been able to figure it out. Right now I'm trying to make the program write "Hi" to the terminal if it recognizes that the 0 button has been pressed. I've looked at a ton of stuff on google but none of it has worked so far.

from PySide6 import QtCore, QtWidgets, QtGui
import sys


WIDTH, HEIGHT = 1200, 700

class Ui_Window(object):

    def setupUi(self, Window):
        Window.setObjectName("Window")
        Window.setFixedSize(WIDTH, HEIGHT)
        Window.setWindowTitle("App") # app title

        self.key = QtCore.Signal()
        self.key.connect(Window, self.on_key)

       
    def keyPressEvent(self, event):
        super(Ui_Window, self).__init__()
        self.key.emit(event)

    def on_key(self, event):
        if event.key() == QtCore.Qt.Key_0:
            print("Hi")

if __name__ == "__main__":
    app = QtWidgets.QApplication(sys.argv)
    Window = QtWidgets.QWidget()
    ui = Ui_Window()
    ui.setupUi(Window)
    Window.show()
    sys.exit(app.exec())
