Tenacity is a general-purpose retrying library for Python that simplifies adding retry behavior to functions and code blocks. It supports configurable stop conditions, wait/backoff strategies, retrying on exceptions or result values, coroutines, and a context manager.

Use cases

• retry flaky network requests until they succeed
• add exponential backoff to API calls
• retry a function a limited number of attempts before giving up
• retry async coroutines on exceptions
• retry only specific exception types
• retry until a function returns an expected value

When to choose

• you need robust, configurable retry logic with backoff in Python
• you want a decorator-based API for retrying functions or coroutines
• you are migrating from the unmaintained retrying library

When to avoid

• you need distributed or cross-service retry coordination
• you want retries managed by infrastructure like a message queue or service mesh
• your use case is simple enough for a hand-written loop
