Dynamically remove a choice option from a form

I have a form like this:

RANGE_CHOICES = (
    ('last', 'Last Year'),
    ('this', 'This Year'),
    ('next', 'Next Year'),
)   

class MonthlyTotalsForm(forms.Form):
    range = forms.ChoiceField(choices=RANGE_CHOICES, initial='this')

It's displayed in the template like this:

{{ form.range }}

In some situations I don't want to show the 'Next Year' option. Is it possible to remove this option in the view where the form is created?

class MonthlyTotalsForm(forms.Form):
    range = forms.ChoiceField(choices=RANGE_CHOICES, initial='this')

    def __init__(self, *args, **kwargs):
        no_next_year = kwargs.pop('no_next_year', False)
        super(MonthlyTotalsForm, self).__init__(*args, **kwargs)
        if no_next_year:
            self.fields['range'].choices = RANGE_CHOICES[:-1]

#views.py
MonthlyTotalsForm(request.POST, no_next_year=True)
