> There is some truth to it. This, however, isn’t due (too much) by how you write the code from a syntax perspective: while coding my Python program I noticed that when the function is run in the context of Lambda, the platform expects to pass a couple of parameters to the function (“event” and “context”). I had to tweak my original code to include those two inputs (even though I make no use of them in my program).

This is just a product of bad design

A better approach would be to decouple all your business logic and provide an interface to it.

e.g.

    MyBusinessLogic
        doSomeBusiness

    MyLambdaRequestHandler
        - handleRequest
          - call myBusinessLogic.doSomeBusiness

That way if you need to move away from AWS Lambda, you can simply remove MyLambdaRequestHandler and any associated unit tests and your application code is unaffected.
