One dimensional convolutions
A convolution of an one-dimensional array with a kernel comprises of taking the kernel, sliding it along the array, multiplying it with the items in the array that overlap with the kernel in that location and summing this product.

array = np.array([1, 0, 1, 0, 1, 0, 1, 0, 1, 0])
kernel = np.array([1, -1, 0])
conv = np.array([0, 0, 0, 0, 0, 0, 0, 0, 0, 0])
# Output array
for ii in range(8):
conv[ii] = (____ * array[____:____+____]).sum()
# Print conv
print(conv)
