How to read lines from a file into a multidimensional array (or an array of lists) in python
list, multidimensional-array, python
Solution
you're almost there, you just need to do:
arr = [line.split(',') for line in open('./urls-eu.csv')]
it iteratively process file line by line, splits each line by comma and accumulates resulting lists into a list of lists. you can drop opening mode (`'r'`) since it's a default one.
Problem
I have a file with a format similar to this: ``` a,3,4,2,1 3,2,1,a,2 ``` I want to read the file and create an array of lists in a way that: ``` array[0] = ['a','3','4','2','1'] array[1] = ['3','2','1','a','2'] ``` How can I do that? So far I am stuck with: ``` f = open('./urls-eu.csv', 'r') for line in f: arr = line.split(',') print arr ``` I am really new to python.
