Question with while loop placement

[Larz60+]

You could make it a bit easier by using a dictionary for demons like:

demons = {
    0: {
        'name': 'DemonOne',
        'health': 25,
        'power': 25,
        'luck': 250,
        'luck_display': 0,
        'armour': 10,
        'attack': 0,
        'attack_calc': 0
    },
    1: {
        'name': 'DemonTwo',
        'health': 25,
        'power': 25,
        'luck': 250,
        'luck_display': 0,
        'armour': 10,
        'attack': 0,
        'attack_calc': 0
    },
    2: {
        'name': 'DemonThree',
        'health': 25,
        'power': 25,
        'luck': 250,
        'luck_display': 0,
        'armour': 10,
        'attack': 0,
        'attack_calc': 0
    }
}

def initialize_demons():
    demons[0]['luck_display'] = demons[0]['luck'] / 10
    demons[0]['attack'] = demons[0]['power'] / 4
    demons[0]['attack_calc'] =  (demons[0]['luck'] / 25) - 1
    demons[1]['luck_display'] = demons[1]['luck'] / 10
    demons[1]['attack'] = demons[1]['power'] / 4
    demons[1]['attack_calc'] =  (demons[1]['luck'] / 25) - 1
    demons[2]['luck_display'] = demons[2]['luck'] / 10
    demons[2]['attack'] = demons[2]['power'] / 4
    demons[2]['attack_calc'] =  (demons[2]['luck'] / 25) - 1

initialize_demons()

# Example usage:
# To get power:
def get_power(demon_no):
    return demons[demon_no]['power']

def get_name(demon_no):
    return demons[demon_no]['name']

def get_attack(demon_no):
    return demons[demon_no]['attack']

def display_some_values(demon_no):
    print('{}: power: {}, attack: {}'.format(get_name(demon_no), get_power(demon_no), get_attack(demon_no)))

# for DemonTwo
display_some_values(1)

When run, results:

Output:
DemonTwo: power: 25, attack: 6.25

You could take this a step further by saving the initial dictionary values as a json file
