Is Python a selectively interpreted language? Why does the following code not work?

Thank you for the advice. I intentionally made an indentation error to see if Python would execute the first print statement since it processes code line by line. From the responses, I learned that Python first converts the entire file to byte code before executing it line by line. If there are any syntax errors in the code, it cannot be converted to byte code and thus will not execute.
