我有一个变量cc，我在其中从会话中获取数据：
cc = request.session['cc_list']
，数据采用以下格式：
[
{"model": "InBound.challengecode", "pk": 1, "fields": {"challenge_code": 50,
"sve_challenge_text": "Good"}},
{"model": "InBound.challengecode", "pk": 2, "fields": {"challenge_code": 48,
"sve_challenge_text": "Voter Not Signed"}}
]
现在我想知道如何迭代它并获取challenge_code和sve_challenge_text的值，因为每当我迭代它的开始时，会按'[', '{', '"'.....这样的字符进行迭代。
我将数据设置为会话：
class ViewChallengeCodes(PermissionRequiredMixin, ExportMixin, SingleTableView):
model = ChallengeCode
table_class = ChallengeCodesTable
permission_required = ('InBound.list_challenge',)
table_pagination = {'per_page': 20}
def get_queryset(self):
challenge_code = super().get_queryset().filter(project__record_status=BaseModel.RecordActive).exclude(record_status=BaseModel.RecordDeleted)
cc_list = serializers.serialize('json', list(challenge_code), fields=('challenge_code', 'sve_challenge_text'))
self.request.session['cc_list'] = cc_list
return challenge_code
提前致谢
