reading CSV file and inserting it into 2d list in python
csv, multidimensional-array, python
Solution
You already have list of lists, which is sort of 2D array and you can address it like one data[1][1], etc.
Problem
I want to insert the data of CSV file (network data such as: time, IP address, port number) into 2D list in Python. Here is the code: ``` import csv datafile = open('a.csv', 'r') datareader = csv.reader(datafile, delimiter=';') data = [] for row in datareader: data.append(row) print (data[1:4]) ``` the result is: ``` [['1', '6', '192.168.4.118', '1605', '', '115.85.145.5', '80', '', '60', '0.000000000', '0x0010', 'Jun 15, 2010 18:27:57.490835000', '0.000000000'], ['2', '6','115.85.145.5', '80', '', '192.168.4.118', '1605', '', '1514', '0.002365000', '0x0010', 'Jun 15, 2010 18:27:57.493200000', '0.002365000'], ['3', '6', '115.85.145.5', '80', '', '192.168.4.118', '1605', '', '1514', '0.003513000', '0x0018', 'Jun 15, 2010 18:27:57.496713000', '0.005878000']] ``` But it is just one dimension and I don't know how to create 2D array and insert each element into the array. Please suggest me what code should I use for this purpose. (I looked the previous hints in the website but none of them worked for me)
