Не удается выполнить валидацию

Question

Нужна проверка на то, что вводимые значения были равны 0 или 1.

Например, ввели значения 1, 1, 0, 1, то тогда будет выполняться сумма.
Если же ввели значения 0, 1, 0, 2, то тогда система выдает сообщение об ошибке:

"Все поля должны быть заполнены значениями 0 или 1".

Но функция def rst(self) не выполняет желаемое. Как правильно реализовать валидацию с таким условием?

def rst(self):
    if not self.lineEdit_10.text() or not self.lineEdit_2.text() or \
       not self.lineEdit_3.text() or not self.lineEdit_4.text() or \
       not self.lineEdit_5.text() or not self.lineEdit_6.text() or \
       not self.lineEdit_7.text() or not self.lineEdit_8.text() or \
       not self.lineEdit_9.text():
       self.lineEdit.setText("Все поля должны быть заполнены значениями 0 или 1")
    else:
        num1 = int(self.lineEdit_10.text())
        num2 = int(self.lineEdit_2.text())
        num3 = int(self.lineEdit_3.text())
        num4 = int(self.lineEdit_4.text())
        num5 = int(self.lineEdit_5.text())
        num6 = int(self.lineEdit_6.text())
        num7 = int(self.lineEdit_7.text())
        num8 = int(self.lineEdit_8.text())
        num9 = int(self.lineEdit_9.text())

        s = num1 + num2 + num3 + num4 + num5 + num6 + num7 + num8 + num9
        r = float(s / 9)
        self.lineEdit.setText(str(r))

Answer 1

def rst(self):
    edits = [self.lineEdit_10, self.lineEdit_2, ...]
    texts = [e.text() for e in edits]
    for t in texts:
        if t not in ('0', '1'):
            self.lineEdit.setText('Все поля должны быть заполнены значениями 0 или 1')
            break
    else:
        s = sum(map(int, texts))
        r = s/9 # float() тут не нужен, и так будет float
        self.lineEdit.setText(str(r))

Или можно так:

def rst(self):
    edits = [self.lineEdit_10, self.lineEdit_2, ...]
    texts = [e.text() for e in edits]
    if all(t in ('0', '1') for t in texts):
        s = sum(map(int, texts))
        r = s/9 # float() тут не нужен, и так будет float
        self.lineEdit.setText(str(r))
    else:
        self.lineEdit.setText('Все поля должны быть заполнены значениями 0 или 1')
