Sure. Here is a code in Python that takes a string as input and returns a Boolean value indicating if the string is a palindrome:

```py
# Use String Indexing in Python to check if a String is a Palindrome

a_string = input('Enter a string:  ')

def palindrome(a_string):
    a_string = a_string.lower().replace(' ', '')
    return a_string == a_string[::-1]

print(palindrome(a_string))

# Returns: True if string is a Palindrome
```
