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
with FileReadBackwards("/tmp/file", encoding="utf-8") as frb:
# getting lines by lines starting from the last line up
for l in frb:
print l
Another example using python3.4::
from file_read_backwards import FileReadBackwards
with FileReadBackwards("/tmp/file", encoding="utf-8") as frb:
# getting lines by lines starting from the last line up
for l in frb:
print(l)
Another way to consume the file is via readline(), in python3.3::
from file_read_backwards import FileReadBackwards
with FileReadBackwards("/tmp/file", encoding="utf-8") as frb:
while True:
l = frb.readline()
if not l:
break
print(l, end="")
