Throttler for asyncio Python

Installation

pip install aiothrottler

Example: multiple tasks throttled

import asyncio
import time

from aiothrottler import Throttler

async def main():
    throttler = Throttler(0.5)
    await asyncio.gather(*[
        worker(throttler) for _ in range(10)
    ])

async def worker(throttler):
    await throttler()
    # Interval of at least 0.5 seconds between prints
    # even though all workers started together
    print(time.time())

loop = asyncio.get_event_loop()
loop.run_until_complete(main())
loop.close()

Example: single task throttled/smoothed

import asyncio
import random
import time

from aiothrottler import Throttler

async def main():
    throttler = Throttler(0.5)
    for _ in range(10):
        await throttler()
        # Interval of at least 0.5 seconds between prints
        # even though each sleep is random
        print(time.time())
        await asyncio.sleep(random.random())

loop = asyncio.get_event_loop()
loop.run_until_complete(main())
loop.close()
