Dear Python and Numpy Users:

My data are in the form of '32-bit unsigned integer' as follows:

myData = np.array([1073741824, 1073741877, 1073742657, 1073742709, 1073742723, 1073755137, 1073755189,1073755969],dtype=np.int32)

I want to get the index of my data where the following occurs:

Bit No. 0–1 Bit Combination: 00

How can I do it? I heard this type of problem first time, please help me.

Artur

not sure I understand the problem, maybe this? np.where((myData & 0x3) == 0)
