In your code you've removed the entire function including the return statement, consequently the loop runs to completion.

Dear All,

I’ve shorted the code be:
SUFFIXES = {1000: ['KB','MB','GB'],
1024: ['KiB','MiB','GiB']}
multiple = 1000
size = 2300
for suffix in SUFFIXES[multiple]:
size /= multiple
if size multiple:
'{0:.1f} {1}'.format(size, suffix)

(Is there a reason you double-spaced all that code? It makes it very
hard to read, and quite difficult to quote, since I had to delete every
other line.)
You wrote your code inline, and not as a function. And you omitted the
return statement. So the loop won't return, it'll run to completion.
Another way to exit a loop early is to use the break statement.

Dear All, Thank you for your advise, it's helpful for me. NB: To DaveA, It was copy-paste from my notepad so the indentation went wrong :( +---+--+---+ | py | h | x0r | +---+--+---+ ■ 1 3 0 E2 C 9 ■ ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

In text mode, naturally, but I get the same result in html mode. The prose was properly spaced, and everyone else's messagesare properly spaced. But the code in that particular message was double-spaced. DaveA ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
