Package Newton’s method for approximating square roots (Case Study: Approximating Square Roots) in a function named newton. This function expects the input number as an argument and returns the estimate of its square root. The program should also include a main function that allows the user to compute the square roots of inputs from the user and python's estimate of its square roots until the enter/return key is pressed.
My code:
import math
tolerance = 0.00001
def newton(x):
estimate = 1.0
while True:
estimate = (estimate + x/estimate) /2
difference = abs(x - estimate**2)
if difference <= tolerance:
break
return estimate
def main():
while True:
x = input("Enter a positive number or enter/return to quit: ")
if x==" ":
break
x = float(x)
print("The program's estimate of the square root of",x,"is", round(newtown(x),2))
print("Python's estimate is:",math. sqrt(x))
main()
it keeps coming up with a syntax error --invalid syntax for line 23 except:
