Hey all.
I would just like to thank you all for extremely good feedback on my problem
with optimizing loops. Thank you all for being so helpful.
Cheers, Trond

Alexander,
The rationale behind the current behavior is to avoid an accidental
propagation of the mask. Consider the following example:
m = numpy.array([1,0,0,1,0], dtype=bool_)
x = numpy.array([1,2,3,4,5])
y =

The code for this is a bit hard to understand. It does appear that it only
searches for a conversion on the 2nd argument. I don't think that's
desirable behavior.
What I'm wondering is, this works fine for builtin types. What is
I can look at it.
Would everyone be satisfied with a solution using regular expressions ?
That is, looking for the following pattern:
pattern = re.compile(r

(.*) # Data
%s? # Zero or one comment character
(.*) # Comments
\s*$ # Trailing white space

Maybe it's because regular expressions make me itch, but I think it's
overkill for this.
The issue here is a result of what I consider a wart in python's string

Hi Christopher,
The advantage of using regular expressions is that in this case it gives you
some flexibility that wasn't there before. For instance, if for any reason
there are two type of characters that coexist in the file to mark comments,
using
pattern = re.compile(comments)
for i,line in

it fails to find anything.
Use index instead?

Well, after all that said, I'm also fine with either approach. Anyway,
I would say that my personal preference is for the one using
'str.index', as it is the simplest one regarding the old code.
Like Christopher, I rarelly (never?) use 'loadtxt'. But this issue
made a coworker to get crazy (he is

I have been poking at the limits of NumPy's handling of powers of
zero. I find some results which are disturbing, at least to me.
Here they are:
In [67]: A = numpy.array([0, 0, 0])
In [68]: B = numpy.array([-1, 0, 1+1j])
In [69]: numpy.power(A, B)
Out[69]: array([ 0.+0.j, 1.+0.j, 0.+0.j])

Thanks Robert. For the record, this is the fixed version:
comment_start = line.find(comments)
if comment_start 0:
line = line[:comments_start].strip()
else:
line = line.strip()
Just as a matter of interest,

Greetings,
Enthought is very excited about our pending wide-release of the
Enthought Python Distribution (EPD). After much effort, we finally
think we're close to the first non-beta release. As one more quality
check, we'd love to impose on you guys one more time to try out a just-
