Python Program

import math def mysqrt(a):

x = a

while True:

y = (x + a/x) / 2.0 if y == x:

break x = y

return x

 

def test_square_root(): a = 1

while a < 26:

mine = mysqrt(a) maths = math.sqrt(a)

print("a =", a, "| mysqrt(a) =", mine, "| math.sqrt(a) =", maths, "| diff =", abs(mine-maths))

a = a + 1 test_square_root()
