17. The following function takes a parameter that is a list of integers; the list has at least one element. It is supposed to find the integer that is the largest and find the position of that integer in the list. The function has two incorrect lines of code that make the function compute the results incorrectly. Several lines are highlighted (bold, underlined) which COULD be incorrect. In the following questions, choose the correct line of code that should be in the function. 1 def findlarge(intlist): 2 largest = 0 3 pos = 0 for i in range(1,len(intlist)): if largest > intlist[i: 4 5 largest = intlist[i] pos = i return (largest, pos) 8 Select one of the following to correct a line of code in the function. a. Line 2 should be: largest = -1 b. Line 2 should be: largest = intlist[0] c. Line 4 should be: for i in range(0,len(intlist): %3D d. Line 4 should be: for i in range(1,len(intlist)-1): e. Line 8 should be: return largest 18. Select one of the following to correct a line of code in…

This decorator will decorate a function that only returns strings and has no arguments. This decorator should reverse the string value returned by the decorated function and return the reversed string. In other words, if a function is decorated by this decorator all of the functional output should be the reverse of its normal output. def…
