Simple retry decorator

Simple retry

Simple retry is a lib that allows you to re-execute functions based on throwing exceptions

Installing

pip install simple-retry

Simple usage

To use the lib you just import the decorator and add on top of the function that you want to retry

import requests

from simple_retry.decorators import retry

@retry(Except=requests.RequestException, retries=5, delay=1)
def func():
    response = requests.get('http://fooo.bar')
    response.raise_for_status()

Coroutines

import asyncio
from simple_retry.decorators import coroutine_retry

@coroutine_retry(Except=Exception, retries=5, delay=1)
@asyncio.coroutine
def coroutine_func():
    yield from (asyncio.sleep(1))

Async

import asyncio
from simple_retry.decorators import async_retry

@async_retry(Except=Exception, retries=5, delay=1)
async def async_func():
    await asyncio.sleep(1)

Parameters

  Except: Exception that will be raised for retry (required)
  retries: Number of retries to be executed (default: 5)
  delay: Waiting time between each execution (default: 0)
  logger: Logger object that will be used to log (optional, default: None)
  level: Log level to log in, example: info, warning, error, exception, critical (default: info)
