Palindrome Coding in Python | Dataford Interview Questions

GEP SMART may validate short text identifiers before processing them. Write a function that determines whether a given string is a palindrome, meaning it reads the same from left to right and right to left.

Compare characters exactly. The comparison is case-sensitive, and spaces, punctuation, and other characters are treated as ordinary characters. Return True when the string is a palindrome and False otherwise.

Formal Specification

Implement is_palindrome(s), where s is a Python string. Return a Boolean value. An empty string and a single-character string are palindromes.

Constraints

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

Function Signature

def is_palindrome(s):
