    Python 2:

    with open ("datafile") as myfile:

    head = [next (myfile) for x in xrange (N) ]

    print head

    Python 3:

    with open ("datafile") as myfile:

    head = [next (myfile) for x in range (N) ]

    print (head)

    Both Python 2 & 3:

    from itertools import islice

    with open ("datafile") as myfile:

    head = list (islice (myfile, N))

    print head
