Use variable inside __init__ to outside __init__

I want to use a variable inside def__init__ outside of def__init__. This is the def__init__ in my class :

class UserResponseSearchForm(forms.Form):
    def __init__(self, *args, **kwargs):
           qry = kwargs.pop('qry')
           super(UserResponseSearchForm,self).__init__(*args, **kwargs)

I want to use variable qry outside def__init__ like this :

class UserResponseSearchForm(forms.Form):
    def __init__(self, *args, **kwargs):
           qry = kwargs.pop('qry')
           super(UserResponseSearchForm,self).__init__(*args, **kwargs)
gejala_id1 = forms.ModelMultipleChoiceField(queryset=Gejala.objects.all().values_list('gejala', flat=True).distinct().filter(gejala__icontains = qry).order_by('gejala'), widget=forms.CheckboxSelectMultiple, required=False)

I use variable qry in gejala__icontains = qry like this:

filter(gejala__icontains = qry)

And it return name 'qry' is not defined. What the problem with that? And how to use the qry variable? Hope anyone can help me.

You need to do this inside __init__:

class UserResponseSearchForm(forms.Form):
    def __init__(self, *args, **kwargs):
        qry = kwargs.pop('qry')
        super(UserResponseSearchForm,self).__init__(*args, **kwargs)
        self.fields['gejala_id1'] = forms.ModelMultipleChoiceField(queryset=Gejala.objects.filter(gejala__icontains = qry).distinct().order_by('gejala'), widget=forms.CheckboxSelectMultiple, required=False)

Note you should not do values_list('gejala', flat=True) for a ModelMultipleChoiceField, because this field expects the objects, not a flat list of strings.
