I want to multiply each element of the list (light) that represents the amount of solar radiation by a value, but I get an error with solar1 but with solar2. Where can I change it to improve it?
light1 = [1,2,3,4]
solar1 = [0.7 * 1 * Powerpv, 0.7 * 2 * Powerpv, 0.7 * 3 * Powerpv, 0.7 * 4 * Powerpv]
light2 = [[1,2,3,4], [5,6,7,8]]
solar2 = [0.7 * 1 * Powerpv, 0.7 * 2 * Powerpv, 0.7 * 3 * Powerpv, 0.7 * 4 * Powerpv], [0.7 * 5 * Powerpv, 0.7 * 6 * Powerpv, 0.7 * 7 * Powerpv, 0.7 * 8 * Powerpv]]
It is an image that looks like.
code
from __future__ import division
from pulp import LpVariable, LpProblem, LpStatus, lpSum, value
import numpy as np
import random, pulp
#PV parameters
Powerpv1 = LpVariable ('Powerpv', 0, None)
Powerpv2 = LpVariable ('Powerpv', 0, None)
light1 = [random.uniform (0, 10) for i in range (24)] #Insolation
solar1 = [0.7 * q * Powerpv1 for q in light1] #pv Power generation
n = 3 # number of repetitions
for k in range (n):
light2 = [[np.random.uniform (0,10) for i in range (24)] for k in range (n)] #Insolation
solar2 = [0.7 * r * Powerpv2 for r in light2] #pv Power generation
print (solar1)
print (solar2)

Answer # 1

Answer # 2
Since light2 is a twodimensional list,
solar2 = [0.7 * r * Powerpv2 for r in light2]
The r in is a list, and the multiplication has failed.Amendment 1: Make light2 a onedimensional list
for k in range (n): light2 = [np.random.uniform (0,10) for i in range (24 * n)] #Insolation ★ Correction solar2 = [0.7 * r * Powerpv2 for r in light2] #pv Power generation
Amendment 2: Broadcast calculation of r as ndarry type
for k in range (n): light2 = [[np.random.uniform (0,10) for i in range (24)] for k in range (n)] #Insolation solar2 = [np.array (r) * 0.7 * Powerpv2 for r in light2] #pv Power generation ★ Correction

I'm not sure what the Powerpv is, but it's probably because of the following error:
Since light2 has a list in the list, the list will come out just by extracting the element one step. And multiplying the list by an integer increments the list itself, not the numbers of the elements in the list.
So, if you want to make it work for the time being, is it like increasing the nesting as shown below?
