Updating a file random acess in Datingand virtual sex games
So, to keep things simple - a quick and dirty alternative approach might be to use from random import randint # Coerce keys to a list, as `dictionary-keyiterator` has no # __getitem__ attribute that would allow integer indices # Note also that this doesn't necessarily guarantee a sorted order # but I guess that doesn't matter if you just want random records key_list = list(fq.keys()) # Select a random key # Note we use len(key_list)-1 as randint endpoints are inclusive random_readname = key_list[ randint(0, len(key_list)-1) ] # Get your record rand_record = fq.get( random_readname ) .
Random access is achieved by setting file pointer to any arbitrary location using . When you write data which exceeds current size of file caused random access file to be extended.Random access file is a special kind of file in Java which allows non-sequential or random access to any location in file.This means you don't need to start from 1st line if you want to read line number 10, you can directly go to line 10 and read.The records do not fit in RAM and would need to be stored on disk.Ideally, I would like to store the reads in a compressed format.
