Python - Coordinates of an array

Question

I'm sorry, I think this is a really trivial question, but...

I have a binary Numpy array, mostly zeros with a few ones. I would like to find the coordinates of all the locations where myArray[myArray == 1]

Please can you help me? Thanks

I'm not sure how you're creating `myArray`, but this could work: `[i for i,v in enumerate(myArray) if v == 1]`. — gen_Eric, Mar 13 '17 at 16:27

np.where(myArray==1)

I guess, should work (assuming its numpy array, based on your indexing example)

If you are using a list (rather than a numpy array), this answer uses enumerate in both a loop and list comprehension: https://stackoverflow.com/a/17202481/1160876
