while reading the CSV file in these lines :
csv_file = open(sys.argv, "r") # reading the csv file into memoery csv_reader = csv.DictReader(csv_file)
when i tried to make a copy of the csv_reader while using the for loop it worked, but any changes to that copy version affected the csv_reader variable, plus
for line in csv_reader: copy = line break for line in csv_reader: print(line)
the second for loop will print everything except for the first line in thencsv_file , why?
I would really be thankful if you gave me the answer thanks in advance !!
