Encapsulate the following Python code from Section 7.5 in a function named my_sqrt that takes a as a parameter, chooses a starting value for x, and returns an estimate of the square root of a.

while True:
y = (x + a/x) / 2.0
if y == x:
break
x = y

Answer 1

def my_sqrt(a, x):
    while True:
        y = (x + a/x) / 2.0
        if y == x:
            break
        x = y
    return x
my_sqrt(25, 1)
