Answer to Question #189942 in Python for FORTUNE AIDOO

Question

Part 2

Write a function named test_sqrt that prints a table like the following using a while loop, where "diff" is the absolute value of the difference between my_sqrt(a) and math.sqrt(a). 

a = 1 | my_sqrt(a) = 1 | math.sqrt(a) = 1.0 | diff = 0.0

a = 2 | my_sqrt(a) = 1.41421356237 | math.sqrt(a) = 1.41421356237 | diff = 2.22044604925e-16

a = 3 | my_sqrt(a) = 1.73205080757 | math.sqrt(a) = 1.73205080757 | diff = 0.0

a = 4 | my_sqrt(a) = 2.0 | math.sqrt(a) = 2.0 | diff = 0.0

a = 5 | my_sqrt(a) = 2.2360679775 | math.sqrt(a) = 2.2360679775 | diff = 0.0

 

Modify your program so that it outputs lines for a values from 1 to 25 instead of just 1 to 9. 

You should submit a script file and a plain text output file (.txt) that contains the test output. Multiple file uploads are permitted.

Answer 1

import math
def my_sqrt(n):
    s=n**0.5
    return s

def test_sqrt():
    a=1
    while a<=25:
        print("a=",a,"|","my_sqrt(a)=",my_sqrt(a),"math.sqrt(a)=",math.sqrt(a),"|","diff=",abs(my_sqrt(a)-math.sqrt(a)))
        a=a+1

if __name__ == '__main__':
    test_sqrt()
