I was hopping some one could look over some coded.

The Question: Elena complains that the recursive newton function in Project 2 includes an extra argument for the estimate. The functions users should not have to provide this value, which is always the same, when they call this function. Modify the definition of the function so that it uses a keyword argument with the appropriate default value, and call the function without a second argument to demonstrate that it solves this problem.

My answer:

import math

tolerance = 0.000001

def newton(n, estimate=1.0):

new_estimate = (estimate + n / estimate) / 2

difference = abs(n - new_estimate ** 2)

if difference <= tolerance:

return new_estimate

else:

return newton(n, new_estimate)

def main():

while True:

number = input("Enter a number or press * to exit ")

if number == '*':

break

number = float(number)

estimate = newton(number)

print("The program's estimate is ", estimate)

print("Python's estimate is ", math.sqrt(number))

if __name__ == "__main__":

main()

Is this right or wrong.

If wrong could you help me fix it.
