Python lambda functions are useful with the map function. We can create more concise code. Python map is a built-in function which applies the given function on every item of iterable(s) and returns an iterator object. lambda_fun_map.py ...
using a lambda function, the same example becomes more elegant and concise : Python import secretsdef gen_token(): return f'TOKEN_{secrets.token_hex(8)}' def test_gen_token(monkeypatch): monkey.('secrets.token_hex', lambda _: 'feedfacecafebeef')assert gen_token() == f"TOKEN...

Function name: A unique name for your Lambda function (for example, multimodal_lambda). Runtime: Node.js 8.10 (Node JS is what the sample Lambda code is written in for this integration. Later, you can explore using other languages for your Lambda, such as Python, Ruby, .NET, Java...
Working with GetObject requests in Lambda This section assumes that your Object Lambda Access Point is configured to call the Lambda function for GetObject. S3 Object Lambda includes the Amazon S3 API operation, WriteGetObjectResponse, which enables the Lambda function to provide customized data and...
Every function in lambda is curried, so we could have also done this:Fn1<Iterable<Integer>, Maybe<Integer>> sumOfEvenIncrementsFn = map((Integer x) -> x + 1) .fmap(filter(x -> x % 2 == 0)) .fmap(reduceLeft((x, y) -> x + y)); Maybe<Integer> sumOfEvenIncrements = sum...
