how to upload and read csv file in django using csv.DictReader?

Question

I am reading csv file through upload and trying to store all values in a list

def upload(request):
    paramFile = request.FILES[\'file\'].read()
    data =          


        

Answer 1

in Python 3, to get the correct type (String not bytes) without reading the full file into memory you can use a generator to decode line by line:

def decode_utf8(input_iterator):
    for l in input_iterator:
        yield l.decode('utf-8')

def upload(request):
    reader = csv.DictReader(decode_utf8(request.FILES['file']))
    for row in reader:
        print(row)
