Instance method as function name in command line

[ksmoore17]

I have defined my lambda function handler as a method on a class. The py file that I want to use as the handler creates an instance of this class.

I want to be able to invoke that method like: python-lambda-local -f instance.method handler.py event.json

handler.py

class LambdaClass:
    def lambda_method(self, event, context):
        ... do stuff

instance = LambdaClass()
