"Sebastian Haase"
My vote would be '-1' ( if that means "I prefer ignore") I'm thinking of an INTERACTIVE platform - and so it would just "look nicer" without to many warnings.
Well, it's only a default so you could always deactivate it (for all interactive sessions in your PYTHONSTARTUP if you wanted).
Actually on that note: I read some time ago about pythons default for printing floats:
0.1 0.10000000000000001 print 0.1 0.1 repr(0.1) '0.10000000000000001' str(.1) '0.1'
Does anyone here have an update on that ?
What I am especially interested in is when I have a list of (floating point) (x,y) positions and then typing in the var-name and getting all these ugly numbers is still very frustration for me ;-)
You can customize python's interactive printing behavior any way you like (in your PYTHONSTARTUP). Here is an example from my old ~/.pythonrc.py (nowadays I almost exclusively use ipython). import pprint PRETTY_PRINT=1 _normal_displayhook = sys.displayhook def _my_displayhook(object): if PRETTY_PRINT: # don't bore us with None if object is not None: pprint.pprint(object) else: _normal_displayhook(object) sys.displayhook = _my_displayhook You could add something to the above to achieve the floating point (or list) formating you desire (``if type(object) is float:...). Since I am a heavy interactive user and found the default floating formating of arrays somewhat clumsy for interactive work, I also wrote some more fanciful formatting code for my Numeric/numarray compatible matrix class that amongst other things offers a number of formating options, including matlab style. I found that this made my life much easier. Thus:
a array([[-9.90000000e+01, -9.72817182e+01, 0.00000000e+00, -7.99144631e+01], [-4.54018500e+01, 4.84131591e+01, 3.03428793e+02, 9.96633158e+02], [2.88095799e+03, 8.00308393e+03, 2.19264658e+04, 5.97741417e+04]]) m = matrix(a) m matrix(''' 1.0E+04 *

m.show('long') matrix(''' 1.0E+04 *

m.show('+') m.show('+') matrix('''
-+++ ++++ ''') etc. Adapting this to e.g. format Numeric arrays similarly via the display hook shouldn't be too hard, I can provide the code if you're interested. 'as
