You can also use python module file_read_backwards. It would be read in a memory efficient manner. It works with Python 2.7 and 3.

It supports "utf-8","latin-1", and "ascii" encoding. It will work with "\r", "\n", and "\r\n" as new lines.

After installing it, via pip install file_read_backwards (v1.2.1), you can read the entire file backwards (line-wise) via:

#!/usr/bin/env python2.7

from file_read_backwards import FileReadBackwards

with FileReadBackwards("/path/to/file", encoding="utf-8") as frb:
    for l in frb:
         print l
