Reading from a text file python

Question

I have a text file which contains a matrix of numbers:

999 999  10  8
3 4 999 999 999 
6 999 2 7 999
999 6 3 5  6
999 9 1 10 999
10 6 999 2 2 999

Answer 1

try that:

matrix = [[int(i) for i in line.split()] for line in open('myfile.txt')]

[edit] if you don't want the first line just read it before.

with open('myfile') as f:
    f.readline()
    matrix = ....
