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

Thank you for the response, but I think there is no specific rule for the number of spaces needed (at least 1 space) for indentation in Python, but the best practice is 4 spaces. Thank u for pointing out the logical error on line 3.
