    fahrenheit = (9.0/5.0) * celsius +32 # The conversion

Answer 1

In the print statement you used 2 spaces to indent the line, while in the next one you put 3 spaces.

Whitespace is significant in Python. Specifically, if you have a certain level of indentation in one line you can't just use another one for the next line.
