Palindrome

1. Write code that determines if a number is a Palindrome

Solution

from typing import Union

def isNumberPalindrome(number: Union[int, str]) -> bool:
    if isinstance(number, int):
        number = str(number)
    return number == number[::-1]

print(isNumberPalindrome("12321"))

• Using Python3.10 that accepts using bitwise operator '|'.

def isNumberPalindrome(number: int | str) -> bool:
    if isinstance(number, int):
        number = str(number)
    return number == number[::-1]

print(isNumberPalindrome("12321"))

Note: Using slicing to reverse a list could be slower than other options like reversed that return an iterator.
