using jupyter lab notebook and a for loop

17. You have seen that the math library contains a function that computes the square root on numbers. In this exercise, you are to write your own algorithm for computing square roots. One way to solve this problem is to use a quess-and-check approach. Tous guess what the square root might be and then see how close your guess is. You can use this information to make another guess and continue guessing until you have found the square root (or,-a close approximation to it). One particularly good way of making guesses is to use Newton's method. Suppose is the number we want the root of and guess is the current guessed answer. The guess can be improved by using guess + x/guess as the next guess
