In Question 3, I used the same set of codes but added an 'else' statement and my output was different 'True True True' instead of 'True True False'. Come someone explain why I had a different (wrong) output?

The code I used is...

def is_palindrome(string):
      for ii in range(len(string)):
         if string[ii] != string[-(ii+1)]:
             return False
         else:
             return True
 
xx = 'cbbeaeacccdceedbdecdabbaddabbadcedbdeecdcccaeaebbc'
yy = 'dabdcdbebddedcdcbbcecbbcdcdeddbebdcdbad'
zz = 'ddbcbeebdbcdddeabbeccaeababaecceababaeaccebbaedddabdbeebcbdd'
print(is_palindrome(xx), is_palindrome(yy), is_palindrome(zz))
