Use the standard library module csv. Something like the following is a cheap and
cheerful solution:


import csv
import numpy

def float_array_from_csv(filename, skip_header=True):
    f = open(filename)
    try:
        reader = csv.reader(f)
        floats = []
        if skip_header:
            reader.next()
        for row in reader:
            floats.append(map(float, row))
    finally:
        f.close()

    return numpy.array(floats)
