Yes, if you use the same editor and reformat source files you 
download before editing them. I have found it to be more 
convenient to use an editor that auto detects common mistakes 
(not unique for Python though).

Yes, I don't think it takes more time to get used to that than to 
get used to braces, but if you nest longer functions within 
functions it is possible to accidentally have a mis-indented 
ending. Not a frequent problem, though. Happens with braces too.
