help with python

Topics: Input, Print, while() Problem Statement: maximum, minimum, and sum of stream of numbers. The purpose of this assignment is to gain experience in python's while loop. Lab Scenario: In this assignment, you will design a simple application which will keep taking input of numbers until user enters 'stop' and displays maximum, minimum and sum of numbers entered. Sample l/O is given below. Lab Procedure: 1. Prior starting of the work consider how to design the nested while loop: a. What would be the loop condition? b. What would be the stopping criteria? 2. Test the application by hand-calculating several values and use the same values to validate the program output. 3. Arrange the main functionality of the code inside a main() function. a. How to define a function: def main(): #body of the function h. To call simply type: main() Sample input/output: Enter a number or 'stop' to stop the program: 1 Enter a number or 'stop' to stop the program: 2 Enter a number or 'stop' to stop the program: 3 Enter a number or 'stop' to stop the program: 4 Enter a number or 'stop' to stop the program: 5 Enter a number or 'stop' to stop the program: stop
