Eventlet Documentation

Code talks! This is a simple web crawler that fetches a bunch of urls concurrently:

urls = [

import eventlet
from eventlet.green.urllib.request import urlopen

def fetch(url):
    return urlopen(url).read()

pool = eventlet.GreenPool()
for body in pool.imap(fetch, urls):
    print("got body", len(body))

Supported Python versions

Currently CPython 2.7 and 3.4+ are supported, but 2.7 and 3.4 support is deprecated and will be removed in the future, only CPython 3.5+ support will remain.
