That depends. How big is the file? Could it include extraneous whitespace
and possibly even comments? How do you expect to deal with bad data? What
version of Python are you using? Who will be maintaining this, a Python
expert or somebody who doesn't know Python very well?

Here's one way (untested but should work):


import numpy
f = open("my data file.txt", "r")
contents = numpy.array([float(line) for line in f])
f.close()
