🚀 Day 63/150 – Check Palindrome String in Python

A palindrome string reads the same forward and backward.

Examples:

• "madam" ✅
• "racecar" ✅
• "python" ❌

Let’s explore different ways to check palindrome strings in Python 👇

🔹 Method 1 – Using Slicing

text = "madam"

if text == text[::-1]:
    print("Palindrome")
else:
    print("Not Palindrome")





✅ Simple and most commonly used method.

---

🔹 Method 2 – Using for Loop

text = "madam"

reversed_text = ""

for ch in text:
    reversed_text = ch + reversed_text

if text == reversed_text:
    print("Palindrome")
else:
    print("Not Palindrome")

✅ Manually reverses the string using a loop.

---

🔹 Method 3 – Using while Loop

text = "madam"

start = 0
end = len(text) - 1
is_palindrome = True

while start < end:
    if text[start] != text[end]:
        is_palindrome = False
        break

    start += 1
    end -= 1

print("Palindrome" if is_palindrome else "Not Palindrome")

✅ Compares characters from both ends.

---

🔹 Method 4 – Taking User Input

text = input("Enter a string: ")

if text == text[::-1]:
    print("Palindrome")
else:
    print("Not Palindrome")






✅ Useful for real-time user input.

---

🔹 Method 5 – Using Function

def is_palindrome(text):
    return text == text[::-1]

text = "madam"

print("Palindrome" if is_palindrome(text) else "Not Palindrome")

✅ Reusable and clean approach.

📌 Key Takeaways

• [::-1] is the easiest way to reverse a string.
• Palindrome means same forward and backward.
• Loops help understand the internal logic better.
• Functions make code reusable and cleaner.
