Solution

The correct Python statement to print out only the even elements would be:

print(var[::2])

This statement uses Python's slice syntax. Here's how it works:

  • The first colon (:) means "start at the beginning".
  • The second colon (:) means "go until the end".
  • The 2 after the second colon means "step by 2".

So, var[::2] will start at the first element of the string (0-indexed), and then take every second element until the end of the string. This will effectively print out the characters at the even indices of the string.
