3s = input("Enter a string: ")

5normalized = "".join(ch.lower() for ch in s if not ch.isspace())
6

7if normalized == normalized[::-1]:
8    print("Palindrome")
9else:
10    print("Not a palindrome")

Output

Enter a string: Never odd or even
Palindrome

What's going on

We normalize by:

Lowercasing all characters
Removing spaces

Then we compare the string to its reverse using slicing.
