src/retry.py (7)
1-5: Add module docstring and fix import formatting.The imports are correct but the module lacks a docstring as flagged by static analysis.
Add this module docstring at the top:
+""" +Retry utility module providing exponential backoff retry decorator. +""" import time import random from functools import wraps from typing import Any, Callable, Optional, Tuple, Type🧰 Tools
🪛 Pylint (3.3.7)
[convention] 1-1: Missing module docstring

10-29: Fix formatting issues in function signature and docstring.The function signature and docstring have trailing whitespace issues identified by static analysis.
Apply this diff to fix trailing whitespace:

42-52: Fix line length and formatting issues in retry loop.The retry loop has line length violations and trailing whitespace.

Consider replacing print statements with proper logging:
+import logging + +logger = logging.getLogger(__name__) # Calculate exponential backoff with jitter wait_time = backoff_base * (backoff_multiplier ** attempts) jittered_wait = wait_time * (1 + random.uniform(-jitter, jitter)) - print(f"Retry {attempts}/{max_attempts} for {func.__name__}.

1-12: LGTM! Standard Python gitignore patterns.The simplified gitignore contains all the essential patterns for a Python project including build artifacts, cache directories, virtual environments, and coverage reports.
src/retry.py (1)
42-58: LGTM! Solid retry logic implementation.The core retry logic is well-implemented with proper exponential backoff, jitter to prevent thundering herd, and appropriate exception chaining. The decorator correctly preserves function metadata and handles both default and custom exception types.
