Python - read numbers from text file and put into list

Question

So like the title says im starting to learn some python and im having trouble picking up on this technique. What I need to accomplish is to read in some numbers and store t

Answer 1

with open('data.txt') as f:
    lis=[map(int,x.split()) for x in f if x.strip()]   # if x.strip() to skip blank lines

   #use list(map(int,x.split()))  in case of python 3.x

this is how map() works:

>>> map(int,'1 2 3 4'.split())
[1, 2, 3, 4]
