how do i compute the average value of every n row of an array?
Question
I have an array ( a ) and need to find the average of every 4th row.
Can I use np.mean to do this? I have tried this but it doesn't work:
means = np.mean(a, step=4, axis=1)
print(means)

You can do that with
means = np.mean(a[::4], axis=1)
Where a[::4] selects every 4th row from a.
