string formatting: http://docs.python.org/library/stdtypes.html#string-formatting-operations here's some common examples: # strings >>> f = 'foo' >>> '%8s' % f ' foo' >>> '%-8s' % f 'foo ' # ints >>> '%04d' % 10 '0010' >>> '% 04d' % 10 ' 010' >>> '% 04d' % -10 '-010' #floats >>> '%.3f' % 1.123456 '1.123' >>> On Feb 25, 2009, at 6:33 AM, yury nedelin wrote: > Chad, > can you describe what's going on in > > >>> [ '%.02f' % x for x in a] > ['1.11', '2.22', '3.33'] > > I have never seen such syntax > thanks > yury > > On Wed, Feb 25, 2009 at 4:53 AM, barakooda <[email protected]> wrote: > > Thanx ! > that really helpful and fast way. > i just have lots of Bboxs to check > thank you thank you > :=) > Barak > > > > On 25 פברואר, 02:00, Chad Dombrova <[email protected]> wrote: > > list comprehension: > > > > >>> a= [ 1.1111, 2.2222, 3.3333] > > >>> [ round(x,2) for x in a] > > [ 1.11, 2.22, 3.33] > > > > if you're rounding these values for the sake of printing them out > then > > you should use: > > > > >>> [ '%.02f' % x for x in a] > > ['1.11', '2.22', '3.33'] > > > > On Feb 24, 2009, at 9:41 PM, barakooda wrote: > > > > > > > > > that what i did > > > but there is function that deal automatically with list or > touple ? > > > that was my question basically > > > > > On 25 פברואר, 00:59, Chad Dombrova <[email protected]> > wrote: > > >> python to the rescue: > > > > >> >>> round( 1.24343, 2) > > >> 1.24 > > > > >> On Feb 24, 2009, at 7:31 PM, barakooda wrote: > > > > >>> for example i have A=(1.2323,1.3232,1.454 > > > > >>> i`m looking for automate function that will output same A but > with 2 > > >>> decimal points less > > > > >>> the new A will be: > > >>> 1.2,1.3,1.4) > > > > >>> i can do it manually but in my script it wont be fun at all :-) > > >>> thank you !!! > > > > > > > > > --~--~---------~--~----~------------~-------~--~----~ http://groups.google.com/group/python_inside_maya -~----------~----~----~----~------~----~------~--~---
