Palindrome Checker in Python | Dataford Interview Questions

A General Motors vehicle diagnostic component receives short string identifiers that may need palindrome validation. Write a function that determines whether a string reads the same from left to right and right to left.

Compare characters exactly as provided. The comparison is case-sensitive, and spaces, punctuation, and digits are treated as ordinary characters. Do not modify, filter, or normalize the input string.

Formal Specification

Implement is_palindrome(s), where:

s is a Python string.
Return True if s is a palindrome.
Return False otherwise.
An empty string and a one-character string are palindromes.

Constraints

0 <= len(s) <= 10^5
s contains standard Python string characters
Comparison is case-sensitive
Spaces and punctuation are treated as ordinary characters

Function Signature
