how can i reverse a list of array in python?

Question

I have a list of arrays:

[array([1,2,3,4],dtype=float32), array([5,6,7,8],dtype=float32)]

How can I reverse this list so that it looks like:

[array([5,6,7,8],dtype=float32), array([1,2,3,4],dtype=float32)]

this?

That is reversing elements in an array. what i want to do here is to reverse a list of arrays — Joo Sohn, Jun 29 '17 at 10:07

Just use negative step:

from numpy import array

a = [array([1,2,3,4],dtype='float32'), array([5,6,7,8],dtype='float32')]
a[::-1]

You can reach with using this:

li = li[::-1]

That way, you assign li with the reversed list of lists.
