Question

Encapsulate the following Python code from Section 7.5 in a function called 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:
a. y = (x + a/x) / 2.0
b. if y == x:
c. break
d. x = y

Answer 1

Answer:

def my_sqrt(a):

   while True:

       x = a

       y = (x + a / x) / 2

       if (y == x):

           break

       else:

           x = y

   print(x)

   return 0

my_sqrt(5)

Explanation:

The above is a function in Python, and the exact copy as code of what is being given in the question. Its a method to find out the square root of a number which is a here. The while loop has been used as being mentioned in the question, and the variables are defined and calculated as being stated.
