RateLimiting

Build Status

Simple Python module providing rate limiting.

Overview

This package provides the ratelimiting module, which ensures that an operation will not be executed more than a given number of times on a given period. This can prove useful when working with third parties APIs which require for example a maximum of 10 requests per second.

Usage

Decorator flavor:

>>> from ratelimiting import RateLimiting
>>> @RateLimiting(max_calls=10, period=1.0)
... def do_something():
...     pass
...

Context manager flavor:

>>> from ratelimiting import RateLimiting
>>> rate_limiter = RateLimiting(max_calls=10, period=1.0)
>>> for i in range(100):
...     with rate_limiter:
...         do_something()
...
