Replace slice of a numpy array with values from another array

Question

Say I've got two numpy arrays which were created this way:

zeros = np.zeros((270,270))
ones = np.ones((150,150))

How can I insert ones in zeros at position [60,60]? I want an array that looks like a "square in the square".

I've tried the following two options:

np.put(empty, [60,60], ones)
np.put(empty, [3541], ones)
np.put[empty, [60:210,60:210], ones)

but the latter yields invalid syntax and the first two don't work either. Has anyone got an idea how this could work?

Answer 1

This is one way you can replace values in zeros with ones.

zeros[60:210,60:210] = ones
