Is there any way in Django Rest framework serializer for ignoring case in choice field?

Question

class MySerializer(serializers.Serializer):
  contract = fields.ChoiceField(choices=(
    ('no', 'no'),
    ('yes', 'yes'),
  ))

So here my input can be one of the following. no, No,Yes,yes

for these do I need to add 2 more entry for Capital one?

contract = fields.ChoiceField(choices=(
    ('no', 'no'),
    ('yes', 'yes'),
    ('No', 'no'),
    ('Yes', 'yes'),

  ))

or is there any way by which we can ignore the case?

If you want to leave it to user, you might have to think of more options like "yes", "Yes", "YES" instead of just "yes, "Yes"

I prefer you convert them to lower and set it on the field by using .lower(), so that you will always get lowercase letters as input
