Duplicate numpy Array Multiple times [duplicate]

Question

I have an array of binary elements size (100,).

I'd like to copy it 8 times, keeping the elements the same and store it as a new array size (800,)

np.copy() can copy it once, but how can I go about copying it 8 times?

Do you mean cycle through the elements 8 times or do you mean repeat each element 8 times and then move onto the next one? — alani

Well here are the two options for the different cases I referred to above: np.tile(a, 8) for the first and np.repeat(a, 8) for the second. — alani

You can use use numpy.repeat. It repeats array's elements by specifying repeat number:

new_arr = numpy.repeat(old_arr, 8)
