AWS - Lambda

Which of the following is the correct way to define a simple AWS Lambda function handler in Python?

Alambda handler(event): print('Hello World')

Bfunction handler(event) { return 'Hello World'; }

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

Ddef handler(): print('Hello World')

Step-by-Step Solution

Solution:

Step 1: Identify correct Python Lambda handler syntax
Lambda handlers in Python must accept two parameters: event and context.
Step 2: Check each option
def handler(event, context): return 'Hello World' correctly defines a Python function with event and context parameters and returns a string. function handler(event) { return 'Hello World'; } is JavaScript syntax. lambda handler(event): print('Hello World') misuses lambda keyword. def handler(): print('Hello World') lacks required parameters.
Final Answer:
def handler(event, context): return 'Hello World' -> Option C
Quick Check:
Python Lambda handler needs event and context [OK]

Quick Trick: Python Lambda handlers always have (event, context) parameters [OK]
