While this is good advice Python doesn't mind if the elif uses
different
indentation to the if. Indeed each elif block could be different, so
long
as its consistent within the block. But that could lead to very wierd
code:

if something:
           do a thing
           and this
elif another :
 do another thing
 and that
elif what:
        something here
        and here
else: pass


Now visually that's a mess but Python won't complain because each
block
is consistent. So to please Python be consistent inside a block, but
to
make it readable be consistent across all blocks!
