[Tutor] file question

[Reggie Dugard]

Joshua,

There's no direct way to get to a specific line in a file, but you can
do it without having to read in the entire file.  If you're using Python
2.3 you can do the following:

for line_number, line in enumerate(open('filename')):
    if line_number == desired_line:
        break
else:
    raise ValueError, 'File too short'
