Answer 1

It sounds like you're wondering how to turn a list into a numpy array of a particular shape. Documentation is here .

import numpy as np
my_list=[3,9,8,7,6,5,4,3,2,1]
# Dropping the first item of your list as it isn't used in your output
array = np.array(my_list[1:]).reshape((3,3))
print(array)

Output

[[9 8 7]
 [6 5 4]
 [3 2 1]]
