```If you'd like to damage_to_enemy from temp_e_hp, you do the following

temp_e_hp -= damage_to_enemy

or

temp_e_hp = temp_e_hp- damage_to_enemy.

To get a random integer between two numbers, you do the folowing:

import random

random.randrange(a, b)

Where it will give you an integer of at least a and less than b.

So in your case, you could do

temp_e_hp -= random.randrange(damage_to_enemy * 0.80 ,damage_to_enemy * 1.2)

Which will do between 80-120% the damage_to_enemy to the enemy.
