Write a Python program called `palindromic.py` that will find words that are palindromes in positional argument which is either a string or a file name.

Anna saw a Honda Civic carrying a kayak. Madam, you are my Mom! Wow!

and I will do my level best to meet you at noon in a racecar outfitted with

radar. You never saw anyone redder. Refer to the rotator or rotor when

you perform your solos. Be sure the stats support the tenet of your argument.
