What needs to be written in order to get an error, it's not a number?

Question

Django

forms.py

def clean(self):
        price = self.cleaned_data['price']
        availability = self.cleaned_data['availability']
        if price < 1:
            raise ValidationError('Цена не может быть ниже 1')
        elif availability < 1:
            raise ValidationError('Количество не должно быть ниже 1')
        elif price != int: - вот здесь в условии что нужно прописать 
            raise ValidationError('Это не число!') -

Answer 1

Answer 2

Maybe just prohibit the use of letters and make a field purely for numbers?
