[Numpy-discussion] RE: Numpy array matching

[Paul F. D. <pa...@pf...>]

They are being held for an administrative reason, my administrator password
won't work, and I haven't gotten the SourceForge people to fix it yet. I
don't understand the administrative reason since I can't get in to see what
it really is -- something about implicit destination, which is greek to me.
I'm at Spam 9 and can't work on it.

Hi Paul,

My emails to numpy-discussion don't seem to
make it.  Is something wrong at sourceforge?
Is it just me?

Thanks,
Sam

If I have a character array t:

>>> t = array(['abcd','aacd','ddfa','qqcd'])
>>> print t
[[a b c d]
 [a a c d]
 [d d f a]
 [q q c d]]

What's the most efficient way to
create an array that contains the indexes
of the rows that match a particular pattern.

If I want to match a 'c' in the third column,
I'd like the array to look like this:

i = array([0,1,3])

Thanks,
Sam
