AIM:

Write a Python program to check whether the string is Palindrome and generate test cases.

Algorithm:

1. Start
2. Get an input from the user by prompting
3. Run a loop form 0 to len/2.
4. Check if the characters are the same both from the start and the end till len/2.
5. If it is, return the result that it is a palindrome.
6. Else, return that it is not a palindrome.
7. Stop the program.

Program:

def Palindrome(string):
    for i in range(0, int(len(string) / 2)):
        if string[i] != string[len(string) - i - 1]:  
            return False
    return True

s = input("Enter a string: ")
c = 1

for i in s:
    if not i.isalpha():
        c = 0
        break  

if c == 0:
    print("Enter a valid string")
else:
    answer = Palindrome(s)
    if answer:
        print("The given string is a palindrome")
    else:
        print("The given string is not a palindrome")

Output:

Result:

Thus, a program to check palindrome has been written and test cases have been written and verified successfully.
