OK, I want to create a nested list in Lisp (always of only integers)
from a text file, such that each line in the text file would be
represented as a sublist in the 'imported' list.
example of a file's content
3 10 2
4 1
11 18
example of programing behavior
(make-list-from-text "blob.txt") => ((3 10 2) (4 1) (11 18))
In a show-off context, it can be reduced to by about 50%, but still
far verbose than ruby or say perl (which is 1 or 2 lines. (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:
[[int(x) for x in line.split()] for line in open("blob.txt")]
Still only 1 line, though.
