write a program in python without using import sys

b) Averaging measurements: Assume that someone has collected a set of measurements and wants some statistics of the entered data. Write a program that asks a user for measurements and prints the average, the maximum, and the minimum measurement. Users should be allowed to enter as many measurements as they want, until entering a negative measurement. The negative measurement should not be processed, but is just used to indicate that the user has finished entering measurements. [Note: do not use a list to store the measurements.]
