I want to make a Python program which implements Newton's Method for square roots. Recall that Newton's Method for calculating square roots by solving 2 = 0 for is certainly converging for initial guess 0 = . Your program sqrtNewtonsMethod will take as input a number a and return the square root of a. Use epsilon=0.0001 as terminating conditional. Test the type of input before any calculations using the appropriate built-in function and if statement(s). If the type is not numerical, return None
