Question

Write a program which has your own versions of the Python built-in functions min and max. In other words, write the functions called maximum(aList) and minimum(aList) that do the job of the built-in Python functions max(aList) and min(aList)respectively. They should take a list as an argument and return the minimum or maximum element . Test your functions with the list [7, 5, 2, 3, 1, 8, 9, 4]. Hint: Pick the first element as the minimum (maximum) and then loop through the elements to find a smaller (larger) element. Each time you find a smaller (larger) element, update your minimum (maximum).

Answer 1

def maximum(aList):

highest = aList[0]

for number in aList:

if number > highest:

highest = number

return highest

def minimum(aList):

lowest = aList[0]

for number in aList:

if number < lowest:

lowest = number

return lowest

print(maximum([7, 5, 2, 3, 1, 8, 9, 4]))

print(minimum([7, 5, 2, 3, 1, 8, 9, 4]))

Step-by-step explanation:

Create a function named maximum that takes one parameter, aList

Initialize the highest as the first number in aList

Create a for loop that iterates through the aList. Compare each number in aList with highest. If a number is greater than highest, set it as new highest.

When the loop is done, return the highest

Create another function named minimum that takes one parameter, aList

Initialize the lowest as the first number in aList

Create a for loop that iterates through the aList. Compare each number in aList with lowest. If a number is smaller than lowest, set it as new lowest.

When the loop is done, return the lowest

Call the functions with given list and print the results
