python-resource-management

What problem does it solve?

Manage resources deterministically in Python using context managers. Resources like database connections, file handles, and streaming state should be released reliably, even when exceptions occur.

Core Features & Use Cases

• Sync and async context managers for resources (database connections, file handles, network streams)
• Unconditional cleanup and robust exception handling to prevent leaks
• Use ExitStack for dynamic resource sets and advanced cleanup patterns
• Streaming state management and accumulated results during resource usage
• Clear guidance on implementing class-based and decorator-based context managers

Quick Start

Define a simple context manager using @contextmanager, then use it in a with block to guarantee cleanup. For example, create a managed_resource() that yields a resource and ensures proper cleanup after exiting the block.
