A parenthesized form is an optional expression list enclosed in parentheses: parenth_form::= "(" [starred_expression] ")" . A parenthesized expression list yields whatever that expression list yields: if the list contains at least one comma, it yields a tuple; otherwise, it yields the single expression that makes up the expression list.

Check if an operation can be paginated. Parameters operation_name (string) -- The operation name.This is the same name as the method name on the client. For example, if the method name is create_foo, and you'd normally invoke the operation as client.create_foo(**kwargs), if the create_foo operation can be paginated, you can use the call client.get_paginator Let’s go over how to use the Python web framework Flask to deploy a Serverless REST API.

Python Lambda function is known as the anonymous function that is defined without a name. Python allows us to not declare the function in the standard manner, i.e., by using the def keyword. Rather, the anonymous functions are declared by using the lambda keyword. However, Lambda functions can accept any number of arguments, but they can return only one value in the The lambda keyword in Python is used for writing lambda expressions. These lambda expressions define small anonymous functions.
