way to package python lambda python files with no requirements.txt

Question

Is there a way to package lambda files that do not have requirements.txt? For using docker or other methods we need to have requirements.txt. Please share ur opinions !

Answer 1

Yes, at a minimum you just need to zip the code. If the handler function is in a file named my_lambda.py, then your zip needs to have this file at the root. If your code has 3rd-party dependencies, you must add them to the zip yourself--they won't get automatically installed by Lambda.
