Question 3 Part 1: Consider the string made up of the uppercase letters of the alphabet: 'ABCDEFGHIJKLMNOPQRSTUVWXYZ Write a Python program that circularly shifts the characters of the above string by n positions to the left. The number n should be a command line argument. Your program should be run like so: python eshift.py 3 The integer argument is the number n. You may assume that n is greater than or equal to zero. positions, A circular shift to the left rotates the letters of the string n positions to the left. Shifting by n = 26 positions is equivalent to shifting by n = 0 positions, shifting by n = 27 positions is equivalent to shifting by n = shifting by n = 28 positions is equivalent to shifting by n = 2 positions, and so on. Your program should print the circularly shifted string; for example: python eshift.py O ABCDEFGHIJKLMNOPQRSTUVWXYZ python eshift.py 1 BCDEFGHIJKLMNOPQRSTUVWXYZA python eshift.py 2 CDEFGHIJKLMNOPQRSTUVWXYZAB python eshift.py 3 DEFGHIJKLMNOPQRSTUVWXYZABC python eshift.py 25 2ABCDEFGHIJKLMNOPQRSTUVWXY python eshift.py 26 ABCDEFGHIJKLMNOPQRSTUVWXYZ python eshift.py 53 BCDEFGHIJKLMNOPQRSTUVWXYZA
