Palindrome Detective 🕵️

A palindrome is a word that reads the same forwards and backwards: racecar, kayak, level, wow. 🔄

Your job: build a function that can spot one.

def shout(word):
    return word.upper() + "!"

print(shout("hello"))     # ➜ HELLO!

return hands the answer back to whoever called the function. That's different from print(), which just splats it on the screen — a returned value can be used in an if, stored in a variable, or tested by me. 🧪

A comparison like word == word[::-1] is already True or False, so you can hand that straight back:

def is_long(word):
    return len(word) > 5

Your mission

Write a function called is_palindrome that takes a word and returns True if it reads the same backwards, False if it doesn't.

I'll test it with racecar, kayak, banana and more. return — don't print! 🎯
