/prog/ - Failing at python

Name: Anonymous 2010-01-27 7:24

All I want to do is read all the lines from a file and put them into a list. This is all. I am failing rather hard. Halp? I'm trying to read each line with a for loop and put them into a list but I can't get it to work.

(define (file->list file)

      (lambda (in)

         (let loop ((collect (list)))

            (let ((line (read-line in)))

               (if (eof-object? line)

                   (reverse collect)

                   (loop (cons line collect)))))))

I know what the things are but I'm not sure how to implement it.

Try a real scripting language:



<?php

$list = file($filename, FILE_IGNORE_NEW_LINES);

?>

Yes, because you're trying to program in Python, but 'implementing' a single function call is beyond your capability. I'll believe that.

Oh, you really need it at all written for you?



file = open('file.txt', 'read').read()

lines = file.readlines().splitlines()

Did you mean lines = open('file.txt','r').readlines()

Use Perl with Tie::File.

I just keep getting errors like 'AttributeError: 'str' object has no attribute 'readlines' for some reason

in perl:

my(@lines)=<>;

What's with all the extra characters?
Did you mean:
@l=<>

Anyone who knows perl should be ashamed of themselves.
