Python Coding challenge - Day 313| What is the output of the following Python Code?

 

Code Explanation:

Lambda Function:

lambda s: s == s[::-1] defines a lambda function that takes a single argument s (a string).

The function checks if the string s is equal to its reverse s[::-1].

s[::-1] uses Python slicing to reverse the string:

s[::-1] means: start at the end of the string, move backwards to the beginning, and include every character.

The expression s == s[::-1] evaluates to True if s is a palindrome (reads the same forwards and backwards), and False otherwise.

Assigning the Function:

is_palindrome = lambda s: s == s[::-1] assigns the lambda function to the variable is_palindrome.

Now, is_palindrome can be used as a function to check if a string is a palindrome.

Calling the Function:

result = is_palindrome("radar") calls the is_palindrome function with the string "radar".

Inside the function:

"radar" is compared with its reverse, which is also "radar".

Since they are the same, the function returns True.

Printing the Result:

print(result) outputs the value of result to the console, which is True.

Output:

The program prints:

True

This means that the string "radar" is a palindrome.
