How can I name a list variable with its first element?

Question

I'm making lists for every line in the text file with the first element being "List[linenumber]", for example, "Line1". However, I need to name these lists so I can use each one later on in the program, so I need to name each list with the first element (e.g. List1 = ["List1", "string", int])

    lines = 0
    user = input ("Enter GTIN-8 Code For Desired Product: ")
    with open('Task2.csv') as File:
        reader = csv.reader(File, delimiter=',', quotechar=',',quoting=csv.QUOTE_MINIMAL)
        for row in reader:
            lines = int(lines)
            lines += 1
            lines = str(lines)
            lists = "List"
            lists = lists + lines
            lists = [lists] + row
            print (lists)

How can I do this? Is there a line of code I can add to the for loop?

Thanks for helping.

this is a bad idea... – Jean-François Fabre May 28 '18 at 13:47 — Jean-François Fabre, May 28 '18 at 13:47

Do you really have to do it this way and saving every list individually in a new variable?

In my opinion a better option would be to use a 2-dimensional List and accessing your elements via their indices, e.g. lines[0][1]. This would be a "list of lists", where the outer list contains your lines, each line in the format of another list.

Glad to hear that. Please always accept an answer, if it answers the question. – lobetdenherrn May 28 '18 at 13:59
@NithilaLogathas besides this answer which is ok, you can also think in storing results (rows) in a dict, where the key is your wanted name. Maybe with the help of `enumerate()` in your `for` loop, to get the row index. – progmatico May 28 '18 at 14:06
