11. Input a string and determine whether it is a palindrome or not; convert the case of characters in the string.

Python

string = input("Enter a string: ")

 

# Check for palindrome

string = string.lower()  # Convert to lowercase for case-insensitive comparison

if string == string[::-1]:

    print(string, "is a palindrome")

else:

    print(string, "is not a palindrome")

 

# Convert case of characters

converted_string = ""

for char in string:

    if char.isupper():

        converted_string += char.lower()

    else:

        converted_string += char.upper()

print("Converted string:", converted_string)
