Palindrome Detection in DSA Python - Build from Scratch

Palindrome Detection

📖 Scenario: You are building a simple program to check if a word is a palindrome. A palindrome is a word that reads the same forwards and backwards, like 'radar' or 'level'. This is useful in games, puzzles, and text analysis.

🎯 Goal: Build a program that takes a word, checks if it is a palindrome, and prints the result.

📋 What You'll Learn

Create a variable with a specific word

Create a helper variable for the reversed word

Compare the original and reversed word

Print whether the word is a palindrome or not

💡 Why This Matters

🌍 Real World

Palindrome detection is used in text processing, coding puzzles, and checking symmetrical patterns in data.

💼 Career

Understanding string manipulation and condition checks is fundamental for programming jobs, especially in software development and data analysis.

1

Create the word variable

Create a variable called word and set it to the string 'racecar'.

DSA Python

# Create a variable called word and set it to 'racecar'
# Your code here

Hint

Use single quotes around the word 'racecar'.

2

Create the reversed word variable

Create a variable called reversed_word that stores the reverse of the string in word using slicing word[::-1].

DSA Python

word = 'racecar'
# Create reversed_word by reversing word using slicing
# Your code here

Hint

Use word[::-1] to reverse the string.

3

Check if the word is a palindrome

Create a variable called is_palindrome that is True if word is equal to reversed_word, otherwise False.

DSA Python

word = 'racecar'
reversed_word = word[::-1]
# Create is_palindrome to check if word equals reversed_word
# Your code here

Hint

Use the equality operator == to compare the two strings.

4

Print the palindrome check result

Print "Palindrome" if is_palindrome is True, otherwise print "Not a palindrome".

DSA Python

word = 'racecar'
reversed_word = word[::-1]
is_palindrome = (word == reversed_word)
# Print 'Palindrome' if is_palindrome is True, else print 'Not a palindrome'
# Your code here

Hint

Use an if statement to check is_palindrome and print the correct message.
