How to read/processes 100 lines at a time from 10000 lines in python? -


how pass/processes 100 lines or lower try: @ time ?

receipt_dict = {} open("data.txt", "r") plain_text: // ** 10000+ lines **     line in plain_text:         hash_value = line.strip()         receipt_dict[hash_value] = 1    try:     bitcoind.sendmany("", receipt_dict) // **here must loop 100 @ time**

with generators. here, load_data_chunks accumulates data in receipt_dict until size exceeds chunk_size , yields main loop below.

def load_data_chunks(path, fname, chunk_size):      receipt_dict = {}      open(fname, "r") plain_text:         line in plain_text:             hash_value = line.strip()             receipt_dict[hash_value] = 1              if len(receipt_dict) > chunk_size:                 yield receipt_dict                 receipt_dict = {}      yield receipt_dict  chunk in load_data_chunks("data.txt", 100):     try:         ...

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } &l
