Edit Question
Title
Body
I want to read a huge text file that contains list of lists of integers. Now I'm doing the following: G = [] with open("test.txt", 'r') as f: for line in f: G.append(list(map(int,line.split()))) However, it takes about 17 secs (via timeit). Is there any way to reduce this time? Maybe, there is a way not to use map.
