You should have the print function indented, usually by 4 spaces. This is
how Python knows which commands to be executed as part of the if block. So
this is what you'll make your code work:

 >>> the_world_is_flat = True
>>> if the_world_is_flat:
...     print("Be careful not to fall off!")
...
Be careful not to fall off!

The interpreter also tries to help you, it puts ... at the begging of the
line (instead of >>>) which means it expect some indentation.
