Hi Folks,
Actually I want to load the csv file for first time only afterwards I don't
want to load the csv files,but everytime when i'm calling the url the same
csv fie is loading for the same operation.How I can restrict it for
multiple loadings?
*Here is my code:*


















*class AutocompleteView(APIView):    def __init__(self):        self.keys =
[]        with open("search_terms_converteds.csv",'r') as file:
reader = csv.reader(file)            for row in reader:
self.keys.append(row[1])            print("constructor execution")
global t        t = Trie()        t.formTrie(self.keys)    def
post(self,request):        key = request.data        print("key:",key)
  suggested_word = t.printAutoSuggestions(key)        return
Response(suggested_word, status = status.HTTP_200_OK)*

*Thank you in advance*

*Regards,*
*Soumen*
