(python would be 3 or 5)).So? Please count the lines: [line.strip().split() for line in file("blob.txt")]The original requirement was for a list of lists of integers:
Actually I read: "Note that the result element is string, not numbers. There's no easy way to convert them on the fly. 3 or so more lines will be needed to do that." So I felt that requirement was dropped, but otherwise, you are right :-)
[[int(x) for x in line.split()] for line in open("blob.txt")]
Still only 1 line, though.
Yep. Regards Tino
