Do the same thing that the parser (or tokenizer) does: say 
"INDENT" and "DEDENT". Or run it through pyindent and read

While theoretically possible, I have never seen whitespace 
confusion induced by different editor settings create a 
syntactically valid program.

And there's tabnanny and tabcleaner if this is a common 
problem for you.
