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

One possible one-liner:

a_list = [map(float, line.split(' ')) for line in a_file]

Note that I used map() here instead of a nested list comprehension to aid readability.

If you want a numpy array:

an_array = np.array([map(float, line.split(' ')) for line in a_file])
