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)

*Why do in my code, it loops to all values and not in Mark Pilgrim’s code?*


(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.
