Features

This package is for reading file backward line by line as unicode in a memory efficient manner for both Python 2.7 and Python 3.

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

It supports “\r”, “\r\n”, and “\n” as new lines.

Usage Examples

An example of using file_read_backwards for python2.7:

#!/usr/bin/env python2.7

from file_read_backwards import FileReadBackwards

f = FileReadBackwards("/tmp/file", encoding="utf-8")

# getting lines by lines starting from the last line up
for l in f:
    print l

# do it again
for l in f:
    print l

Another example using python3.3:

#!/usr/bin/env python3.3

from file_read_backwards import FileReadBackwards

f = FileReadBackwards("/tmp/file", encoding="utf-8")

# getting lines by lines starting from the last line up
for l in f:
    print(l)

# do it again
for l in f:
    print(l)
