Переменная в названии кнопки Python PyQt5

Question

Есть кнопки: Button0, Button1, Button2 и Button3 и переменная f.

При нажатии на кнопку Button0:

global f
f = 0

def Button0_clicked(self):
        f + 1
        btn = "Button" 
        btnname = btn + str(f)
        self.ui.btnname.show()
        self.ui.btnname.settext('settext')

Выводит ошибку -

AttributeError: 'Ui_MainWindow' object has no attribute 'btnname'

Как сделать так, чтобы он считал btnname переменной, а не именем кнопки (или же есть другой вариант как это сделать)
