Retrying is a Python decorator library that simplifies adding retry behavior to functions. It wraps a function call and automatically re-executes it when exceptions occur or when result conditions aren't met, without requiring manual loop logic. The library handles the common patterns: retrying forever, stopping after a maximum number of attempts, stopping after elapsed time, waiting between retries with fixed delays, random jitter, or exponential backoff. You can customize which exceptions trigger a retry, inspect return values to decide whether to retry, and combine multiple stop and wait conditions.
The decorator approach keeps retry logic separate from the function body, making it easy to add to existing code. It's useful for handling transient failures in network calls, database operations, or any operation that might temporarily fail but succeed on retry.
Use it for
- Retry flaky network requests with exponential backoff to avoid overwhelming remote services.
- Handle temporary database connection failures by retrying up to a maximum number of attempts.
- Implement polling logic that waits between checks for a resource becoming available.
- Wrap unreliable I/O operations with automatic retry on specific exception types.
- Add retry behavior to distributed system calls with configurable backoff strategies.
