how to write makefile for python?

Reversing a 1-D array. Write a Python function that given an array A of numbers returns an array B that has t?

• a. What should the output of the function be for A = {3, 2, 1, 5, 9}? b. Write the Python function. Include detailed comments. The name of the function should be def ReverseArray(A). B should be returned. c. Evaluate the Python function for arrays of length 1, 5, and 10. Report each input and output. I know A. its B = [9,5,1,2,3] And C will be simple once i can determine a working code, but everything I've tried turns up errors

• Answer:

  python already offers the "reversed" builtin, which allows you to reverse any iterable: >>> r=reversed([1,2,3]) >>> r <list_reverseiterator object at 0x1eb3290> >>> list(r) [3, 2, 1] >>> r = reversed("abcdefghi") >>> r <reversed object at 0x1eb3350> >>> list(r) ['i', 'h', 'g', 'f', 'e', 'd', 'c', 'b', 'a'] >>>
