tiny-retry-gw 0.2.1

A tiny retry helper for synchronous Python code.

tiny-retry v0.2.1

tiny-retry is a tiny package for retrying (synchronous) Python functions when they raise exceptions, designed to keep things light and simple.

Installation

pip install tiny-retry-gw

Usage

from tiny_retry import retry, retry_infinite

def foo():
    # Replace this code with something that can raise the exception(s) you want to retry on.
    ...

# This will try foo() 6 times, with a delay of 3.1 seconds between retries, and it will only retry when ConnectionError is raised.
result = retry(foo, tries=6, delay=3.10, exceptions=(ConnectionError,))

# This will try foo() infinitely, with a delay of 3.1 seconds between retries, and it will only retry when ConnectionError is raised.
result = retry_infinite(foo, delay=3.10, exceptions=(ConnectionError,))

Parameters

• func: function to call.
• tries: how many times to attempt the function (must be >= 1).
• delay: delay in seconds between retries.
• exceptions: a tuple of exceptions that should trigger another attempt.
• *args, **kwargs: optional positional and keyword arguments to be passed into func.

If all attempts fail, retry reraises the last exception so the caller can handle or log it.

Notes

• retry_infinite does not take tries as a parameter.

Development
