Python: Concurrency with asyncio (asyncio 기반 비동기 프로그래밍)
Thread vs Asyncio 스레드나 코루틴을 통해 콘솔 에니메이션을 구현할 수 있다. 먼저 스레드를 이용하는 코드이다. Console animation can be implemented with either threads or coroutines. First, with thread. import threading import itertools import time import sys class Signal: go = True def spin(msg, signal): write, flush = sys.stdout.write, sys.stdout.flush for char in itertools.cycle('|/-\\'): status = char + ' ' + msg write(status) flus..
Web downloads in three different styles - sequential download - concurrent.futures - asyncio With heavy input/output workload, we can make the best out of concurrency. Below is the code that downloads flag gif files sequentially. import os import time import sys import requests POP20_CC = ('CN IN US ID BR PK NK BD RU JP' 'MX PH VN ET EG DE IR TR CD FR').split() BASE_URL = 'http://flupy.org/data/..
