Indentation is not invisible.

        Can you really not see that this text
        is indented? If so, your news program 
        is seriously broken.

Discipline. Choose a standard indent and stick to it.

You can use tabs, or spaces. If you use spaces, you can choose 4 spaces, 
or 8, or any number, but whatever you choose, stick to it no matter what 
editor you use. Good editors will let you use the tab key to indent with 
spaces. Bad editors (e.g. Windows Notepad, and I feel your pain if you 
have to use it) force you to manually insert spaces.

Especially never mix tabs and spaces in the same file. If you're editing 
an existing file, you must follow whatever indent standard is already in 
use.

You can also pass the -t option when launching the Python interpreter to 
warn about mixed tabs and spaces.
