如何检查 Python 应用程序是否在 AWS lambda 函数中运行? [英] How to check if Python app is running within AWS lambda function?

问题描述

我有一个连接到数据库的 Python 应用程序，我希望数据库凭据在本地环境(用于测试)或 lambda 函数(用于生产)中运行时不同.

I've got a Python application that connects to a database and I would like the db credentials to be different when it's running in local env (for testing) or within a lambda function (for production).

有什么方法可以从 Python 应用程序中检测它是否在 lambda 函数内运行?

Is there any way, from the Python app, to detect that it is running inside the lambda function?
