Read list in python [duplicate]

Question

I have this list of lists that looks like this:

vrt = [[1,3,3,8,5,4,2,1,5,6],
       [2,4,3,3,6,8,1,3,5,6],    
       [4,5,6,4,7,4,3,6,4,7],
       [2,8,7,0,0,7,4,7,8,0],
       [2,3,4,7,0,8,7,6,3,8],
       [3,7,9,0,8,5,3,2,3,4],
       [1,5,7,7,6,4,2,3,5,6],
       [0,6,3,3,6,8,0,6,7,7],
       [0,1,3,2,8,0,0,0,0,0],
       [3,1,0,3,6,7,0,5,3,1],
       [1,3,5,7,0,8,6,5,3,1],
       [3,6,3,1,3,5,8,7,5,1],
       [4,3,6,0,0,8,4,7,5,3],
       [3,5,6,8,6,3,1,3,5,2]]

And I need to write a function that will read evey line, sum all the integers in every line and return the result of every line as new list, in case of this particular list result would be [38, 41, 50...42], so just sum of every list.

Up till now I tried doing it like this

def po_vrstah(vrt):
    s = []
    line = vrt.read().split('\n')
    vsota = sum(line)
    s.append(vsota)
    return s

So I did a little research and apparently those read and split ('\n') can be used only reading files I think?

So my question is, how can I use similar approach solving this problem? Is there a way to read lists in similar way as files?

Answer 1

It's much more simple:

>>> print map(sum, vrt)
