Project description
file_read_backwards
Memory efficient way of reading files line-by-line from the end of file
Free software: MIT license
Documentation: https://file-read-backwards.readthedocs.io.
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 # do it again for l in frb: print l
Another example using python3.3:
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) # do it again for l in frb: print(l)
