Answer 1

From the QueryDict.items() ofQueryDict objects[Django-doc]

Like dict.items(), except this uses the same last-value logic as getitem () and returns an iterator object instead of a view object.

And the QueryDict.__getitem__(key) as stated

Returns the value for the given key. If the key has more than one value, it returns the last value . Raises django.utils.datastructures.MultiValueDictKeyError if the key does not exist.

So you can use QueryDict.getlist(key, default=None) as stated

Returns a list of the data with the requested key. Returns an empty list if the key doesn't exist and default is None. It's guaranteed to return a list unless the default value provided isn't a list.

In your views.py

from django.http import QueryDict
from django.shortcuts import render

def get_copy(request):
    data = QueryDict('grub_id__in=Yelek&grub_id__in=Tunik&grub_id__in=Tulum&grub_id__in=Tshirt')
    return render(request, 'test.html', {'get_copy':data.getlist('grub_id__in')})

And in your templates

{{get_copy}}

Output

['Yelek', 'Tunik', 'Tulum', 'Tshirt']
