AWS - Lambda

Which of the following is the correct syntax for a Python AWS Lambda handler function?

Afunction handler(event, context) { return 'Hello World'; }

Bdef handler(event, context): return 'Hello World'

Clambda handler(event, context): print('Hello World')

Ddef handler(): return 'Hello World'

Step-by-Step Solution

Solution:

Step 1: Identify Python function syntax
In Python, functions are defined with def and must include parameters if expected. The handler must accept event and context.
Step 2: Check each option
def handler(event, context): return 'Hello World' correctly defines a Python function with two parameters and returns a string. function handler(event, context) { return 'Hello World'; } is JavaScript syntax. lambda handler(event, context): print('Hello World') misuses lambda keyword. def handler(): return 'Hello World' lacks parameters.
Final Answer:
def handler(event, context): return 'Hello World' -> Option B
Quick Check:
Python Lambda handler syntax = def with event, context [OK]

Quick Trick: Python Lambda handler uses def with event and context [OK]
