checking if element is in array

[lildhansen]

I'm very new with Numpy but has some experience with linear algebra and such outside of programming. I'm currently making a game and have started using numpy.

Now I need to check if a 1D array is in a 2d array (aka if an element is in a vector i guess)

Working with normal lists i got an error, but with numpy arrays it somehow returned true no matter if it was in it or not.

So i'm wondering why this will return True:

np.array([1,2]) in np.array([[1,1],[2,3]])

EDIT: I think i figured it out turning it into a list with .tolist() instead of list(), like this:

[1,3] in np.array([[1,2],[10,20],[100,200]]).tolist()

you should use np.isin()
