If it is a single file that never changes just read it into a list:
with open(filename) as f:
cached_lines = list(f)
If that alone takes about 4 seconds the runtime of your script is spent
reading the file from disk. An SSD might help then ;)
In some situations you could delay reading line n until that line is
actually needed. This may speed up your script for cases where all requested
lines are near the beginning of the cached file.
