Write idempotent code.Writing idempotent code for your functions ensures that duplicate events are handled the same way. Your code should properly validate events and gracefully handle duplicate events. For more information, seeHow do I make my Lambda function idempotent?. ...
Understanding how len() works with different data types helps you write more efficient and concise Python code.Using len() in Python is straightforward for built-in types, but you can extend it to your custom classes by implementing the .__len__() method. This allows you to customize what...
