Question

How to read a file in reverse order using python? I want to read a file from last line to first line.

Answer 1

You can also use python module file_read_backwards.

After installing it, via pip install file_read_backwards (v1.2.1), you can read the entire file backwards (line-wise) in a memory efficient manner 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

It supports "utf-8","latin-1", and "ascii" encodings.

Support is also available for python3. Further documentation can be found at http://file-read-backwards.readthedocs.io/en/latest/readme.html
