Python Code Please

Specific things we would like this function to do: a) Take in one input argument that represents a dataset in the form of a 1D numpy array. This array should contain a set of numbers of arbitrary size. b) To make sure that you didn't just randomly download the function somewhere and to ensure that you understand the concept of scope, declare the variable "writtenBy" and assign your name as a value to it somewhere in the function, but don't return/output this value. c) The function should return the median absolute deviation as an output. d) Make sure the function has a clear header - a block of comments at the beginning of the function - as to what inputs the function assumes, what outputs it produces and when it was written
