The fastest way to read input in Python

Question

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 li         


        

Answer 1

The easiest speedup would be to go for PyPy http://pypy.org/

The next issue to NOT read the file at all (if possible). Instead process it like a stream.
