Iterative Palindrome Function in Python

In this exercise, you will develop a Python program with an iterative function to check if a string is a palindrome (symmetric). This exercise is perfect for practicing function definition, loops, and string manipulation in Python. By implementing this function, you will gain hands-on experience in handling function definitions, loops, and string manipulation in Python. This exercise not only reinforces your understanding of functions but also helps you develop efficient coding practices for managing user interactions.

Objective

Develop a Python program with an iterative function to check if a string is a palindrome (symmetric). For instance, "RADAR" is considered a palindrome.

Example Python Exercise

 Copy Python Code 
# Function to check if a string is a palindrome using iteration
def is_palindrome(s):
    # Convert the string to lowercase to make the check case-insensitive
    s = s.lower()

    # Loop through the string from both ends towards the middle
    for i in range(len(s) // 2):
        # Compare characters at the start and end positions
        if s[i] != s[len(s) - i - 1]:
            return False  # Return False if characters don't match

    return True  # Return True if the string is a palindrome

# Example strings to test
test_strings = ["RADAR", "hello", "madam", "world"]

# Check if each string is a palindrome
for test_string in test_strings:
    result = is_palindrome(test_string)
    print(f"Is '{test_string}' a palindrome? {result}")

 Output

python palindrome_check.py
Is 'RADAR' a palindrome? True
Is 'hello' a palindrome? False
Is 'madam' a palindrome? True
Is 'world' a palindrome? False
