Warm invocations sent by X-Lambda are received by a Lambda function, which needs to respond accordingly.\n\nThis **X-Lambda Helper** project helps to handle warm invocations in Python functions.\n\n## Requirements\n\n- [Python 3.6+](https://www.python.org/downloads/)\n- [AWS account](https://aws.amazon.com/account/)\n\n## Quick start\n\n1. Install X-Lambda Helper: `pip install xlambda_helper`.\n2. Decorate your [Lambda handler](https://docs.aws.amazon.com/lambda/latest/dg/python-programming-model-handler-types.html) following the example below:\n3. Deploy your code in AWS Lambda.\n\n### Usage example\n\n```python\nimport xlambda_helper\n\n\n@xlambda_helper.warm()\ndef handler(event, context):\n    # Your original code goes here\n    x_men = [\n        {'Charles': 'Professor Xavier'},\n        {'Logan': 'Wolverine'},\n        {'Jean': 'Phoenix'},\n        {'Scott': 'Cyclops'}\n    ]\n\n    return x_men\n```\n\n## About\n\nX-Lambda Helper will be executed every time your handler is invoked by AWS Lambda. It will check whether the invocation is a warming request coming from X-Lambda. If not, it will run your handler code normally. If yes, it will short-circuit to return a default answer and will not execute the handler function.\n\nWhen handling warm requests, X-Lambda Helper will automatically adjust your function behavior:\n\n- Check whether it was a cold start\n- Sleep for a period of time, if needed\n- Defer to your original handler function, if invocation is not a warm request",
