Hey @sradha, 

def lambda_handler(event, context): 

Here def is for defining a function with a handler name as lambda_handler, it can be anything depending on your use. 

event :- this is the type of data that is being passed to your handler. Generally it is of python dict type but again it can be of any type. 

context:- this is used to provide runtime information to your handler. This is of LambdaContext type.

for more details on this refer this documentation from amazon.
