Reading file string into an array (In a pythonic way)

Question

I\'m reading lines from a file to then work with them. Each line is composed solely by float numbers.

I have pretty much everything sorted up to convert the lines in

Answer 1

If you want a numpy array and each row in the text file has the same number of values:

a = numpy.loadtxt('data.txt')

Without numpy:

with open('data.txt') as f:
    arrays = list(csv.reader(f, delimiter=' ', quoting=csv.QUOTE_NONNUMERIC))

Or just:

with open('data.txt') as f:
    arrays = [map(float, line.split()) for line in f]
