What about introducing a method for text streams that reads the lines
from the bottom? Java has also a ReversedLinesFileReader with Apache
Commons IO.
1) Read the entire file and decode bytes to text
2) Split into lines
3) Iterate backwards over the lines
Tada! Done. And in Python, quite easy. The downside, of course, is
that you have to store the entire file in memory.
Why not just do:
tail = collections.deque(text_stream, maxlen = nr_of_lines)
tail.reverse()
