Question

Problem 4. (Root Finding) Write a program root.py (a variant of the sqrt.py program we dicussed in class) that accepts k (int), c (float), and epsilon (float) as command-line arguments, and writes to standard output the kth root of c, up to epsilon decimal places.

Answer 1

The code with related comments areas below:

import sys

if len(sys.argv) is not 4:                       #check if all the arguments are present
   print ('Number of arguments not satisfied')   
   exit()                                       #if not present print the statement and exit
  
root_number = int(sys.argv[1])                   #load the arguments into variables
number = float(sys.argv[2])
decimal_number = int(sys.argv[3])
root = number**(1/root_number)                   #caluclation of the root
rounded_root = round(root, decimal_number)       #rounding the root the epsilon value
print ('The '+str(root_number)+'th root of '+str(number)+' is '+str(rounded_root)) # printing the result
