--description--

Given two strings, determine if the second string is a mirror of the first.

• A string is considered a mirror if it contains the same letters in reverse order.
• Treat uppercase and lowercase letters as distinct.
• Ignore all non-alphabetical characters.

--hints--

is_mirror("helloworld", "helloworld") should return False.

from unittest import TestCase
TestCase().assertIs(is_mirror("helloworld", "helloworld"), False)`)

is_mirror("Hello World", "dlroW olleH") should return True.

({test: () => { runPython(`
from unittest import TestCase

is_mirror("RaceCar", "raCecaR") should return True.

({test: () => { runPython(`
