Numerical Computing with Python

The basic Python way

We can initialize an empty list, read the file line by line, split each line, and append the second element to our list:

evens = []with open as f:    for line in f.readlines():        evens.append(line.split()[1])

Of course, you can also do this in a one-liner:

evens = [int(x.split()[1]) for x in open('evens.txt').readlines()]

We are just trying to go step by step, following the Zen of Python: simple is better than complex.
