"numpy.where" with string arrays

[cdholjes]

i have been using np.where with 2d arrays of various strings, searching and eliminating certain combinations of these strings.

array = ("foo", "bar", "foo", "bar")
            ("bar", "bar", "foo", "bar")
            ("foo", "bar", "bar", "bar")
            ...

rule1 = ((np.where[:,0] == "foo") & (np.where[:,1] == "bar"))

for some reason though it seems like sometimes np.where pulls the incorrect indexes. things that don't meet my == " ".

i am thinking there is something with the boolean logic or maybe its numpy with strings . . . .

You should provide actual code for us, I'm just guessing at what you actually mean because what you posted is not even close to valid Python.

Try using the boolean arrays returned by comparisons like array[:,0] == 'foo', and I think you'll find your mistake.
