Stop Forgetting to Close Your Resources

February 5, 2026

Whether you're dealing with file I/O, database connections, or network sockets, forgetting to explicitly close the resource after use leads to leaks and instability, especially when exceptions occur. If you code in Python (or languages supporting similar patterns), embrace the 'with' statement (the context manager). It guarantees that the resource's cleanup method is called automatically, even if an error crashes the code block. It makes your code infinitely safer and much more reliable.
