linecache-light 0.1.3

A python package that can fast random access any lines in a large file without high memory cost.

LineCache caches the line position of a file in the memory. Everytime it access a line, it will seek to the related postion and readline(). Noticing that it may cost some time when you first cache lines of a file.

Usage:

from linecache_light import LineCache

linecache = LineCache(‘a.txt’, cache_suffix=’.cache’)

num_lines = len(linecache)

line_0 = linecache[0]

line_100 = linecache[100]

line_indexing= linecache[[2,3,4,5]]

line_indexing = linecache[-1]
