[textRPG]How to keep random creating of class and class atrributes every time i run a program[Python]

I am trying some text based rpg game as a beginner in python. But i am struggling to get done one thing.
If i use while loop to run program 5 times. So i want repeat killing monster but without saving his attributes.
If you run this code, character kills a monster in couple of moves and appends his experience to himself and monster hp decreases to <= 0 and dies.
Looping whole program does not work, randomly created monster is still the same, i just want to create new monster with new random attributes every time i loop program. It is possible? I am new to this and can't figure it out at this moment. Some tips ?
Here is some code but without while loop: final output is to loop this menu and fight simulator to gain exp and items from random monsters.
import random
import time
# List of items to drop
normal_items = ['Copper ore', 'Apple', 'Animal skin', 'Stone', 'Feather', 'Rotten egg', 'Bag of sand', "Simple dagger", "Blue flower"]
rare_items = ['Energized wand', 'Staff of purity', 'Enhanced gloves', 'Adamant chest plate']
legendary_items = ['Crown of Immortality', 'Robe of fire-dragon']
drop_chance_dice = random.randint(1, 100)
# Simple drop chance function
def dice():
if drop_chance_dice <= 70:
random_choice = (random.choice(normal_items))
print(f"You got: {random_choice} ")
if 70 <= drop_chance_dice <= 98:
random_choice = (random.choice(rare_items))
print(f"You got: {random_choice} ")
if 99 <= drop_chance_dice <= 100:
random_choice = (random.choice(legendary_items))
print(f"Congratulations! You got an legendary item: {random_choice}")

I tried: to create new unique monster with new randomly created attributes every time i run program. I used while loop but monster is not "respawning"
I expect: Some sort of simulator, after i kill monster, program creates new one and my character gains experience and items every fight.
I wonder: If there is some method to makes this class unique every loop.

Here is HOW-TO to achieve all goals in your question:
each time generate monsters with different parameters
respawn monsters
First you create 3 sepreate functions that would return a new monster - the class of returned value is always the same (Monster) but they return new instances on each call:
def get_rat():
return Monster("You fight vs: \n", "Rat", ...)
def get_giant_rat():
return Monster(...)
def get_rat_boss():
reutrn Monster(...)
You will also need to modify how you select monsters. I would suggest to create list of functions - so instead of selecting a monster you select a function, that generates monster:
# This should replace the list_of_mob
list_of_mob_generators = [get_rat, get_giant_rat, get_rat_boss]
And the last - you should select monster on each loop interation in main menu (so the monster could respawn). The shortest way is to change your global variable:
event_mob = None # we change event_mob initially to None - we will select in later
def menu_dungs():
global event_mob # this is new
asking = input("Where do you want to go?: 1.Rat Nest or 2.Northern Forest :")
if asking == "1":
event_mob_generator = random.choice(list_of_mob_generators) # get one of the functions
event_mob = event_mob_generator() # call the function to get monster
print("You entering rat nest.. good luck!\n")
time.sleep(1)
print("Some ugly creature stays on your way!")
print(f"{event_mob.name} is looking at you!")
# and this condition has changed, since we do not have one instance of each monster anymore
if event_mob.name == 'Rat':
introduction_of_monster_ratnest(event_mob)
escape_or_fight()
elif event_mob.name == 'Giant Rat':
introduction_of_monster_ratnest(event_mob)
escape_or_fight()
elif event_mob.name == 'Rat Boss':
introduction_of_monster_ratnest(event_mob)
escape_or_fight()
else:
print("Something went horribly wrong.. Don't even ask..")
... # and so on
and of course do not forget a while loop for main menu =)
while True:
menu_dungs()

Thanks for help, program works as i wanted but still shows me 8 yellow errors in attack() function. Cannot find reference 'hp' in 'None' etc.
maybe because this event_mob = None ?
Could you run this code and see what is going on ? very likely i did put something in wrong place..

an enemy class in a RPG-game

I am in the midst of making an RPG game in Python.
I have made different classes, but I am having problems with one of my enemy types. It is a spider, and to spice things up, I tried to make the spider do dot (damage over time). It is not guaranteed poison damage, but when it does poison you, it stacks.
This is my parent class (enemy):
class Enemy():
def __init__(self, number_of, name):
self.number_of = int(number_of)
self.name = name
self.hp = 20 * self.number_of
self.dmg = 2 * self.number_of
def attack(self):
print(f"you now have {round(class1.hp)} health" + "\n")
def appearing(self):
if self.number_of > 1:
print (f"{self.number_of} {self.name}s have appeared")
else:
print(f"A {self.name} has appeared")
print (f"They have {self.hp} health")
Note: the class1 is the player
This is my spider class:
class Spider(Enemy):
posion_dmg = 0
def __init__(self, number_of, name):
Enemy.__init__(self, number_of, name)
self.posion_dmg = 0
def attack(self,player):
if self.posion_dmg > 0:
dot = 2 ** (self.poison_dmg + 1)
player.hp -= dot
print ("you are posioned" + "\n")
print (f"it deals {round(dot)} damage")
dmg = random.uniform(1.2 * self.dmg, 1.8* self.dmg)
player.hp -= dmg
print ("The spider(s) bite(s) you. ")
print(f"It deals {round(dmg)} damage")
if randint(1,4) == 1:
self.poison_dmg += 1
if self.number_of == 1:
print ("The spider poisons you")
else:
print ("The spiders poison you")
return Enemy.attack(self)
def appearing(self):
print ("*Spiders have a chance to hit you with poison that deals damage over time - this stack exponentially*")
return Enemy.appearing(self)
When I go in combat with the spider, and the randint is 1, it says that "Spider" has no attribute "poison_dmg", but I made it an attribute, right?

im kind of a newbie to python but i've successfully gone through the "Make Your Own Python Text Adventure" guide and i got a basic grip of how this works, although i do not completely understand how you're making the dot work, i think your problem is:
class Spider(Enemy):
posion_dmg = 0
def __init__(self, number_of, name):
Enemy.__init__(self, number_of, name)
self.posion_dmg = 0 <-----------------------HERE
in combination with this:
def attack(self,player):
if self.posion_dmg > 0:
dot = 2 ** (self.poison_dmg + 1)
player.hp -= dot
print ("you are posioned" + "\n")
print (f"it deals {round(dot)} damage")
dmg = random.uniform(1.2 * self.dmg, 1.8* self.dmg)
player.hp -= dmg
print ("The spider(s) bite(s) you. ")
print(f"It deals {round(dmg)} damage")
if randint(1,4) == 1: <----------------------------HERE
self.poison_dmg += 1
if self.number_of == 1:
print ("The spider poisons you")
else:
print ("The spiders poison you")
The if statement is indented within a def that begins with another if poison_dmg > 0, and is not because you've already defined it to be 0 in the init.
i would invert the order of the if statements within the attack function, so you first generate a poison_dmg value, and then you evaluate wether or not that value is greater than 0.
Hope it works!

Python gives me "None" when trying to print a function

I am quite new to python, having only toyed with it for a few days now. I am trying to cobble together a program to show off a battle system I had in mind. My issue is that I keep getting "None" produced when I try to print
import os
class Player():
def __init__(self, name, hp, maxhp, strength, intel, charm, level):
self.name = name
self.hp = hp
self.maxhp = maxhp

self.intel = intel
self.charm = charm
self.level = level
def attack(self, Enemy):
Enemy.hp -= self.strength

self.name = name
self.hp = hp
self.maxhp = maxhp

self.charm = charm
self.level = level
def Start():
Player.hp = 100
Player.maxhp = 200
Player.strength = 30
Player.intel = 10
Player.charm = 43
Player.level = 23
nameSelection()
def nameSelection():
os.system('cls')
Player.name = input("Please enter your name\n==>")
print("==>")
gameStart()
def gameStart():
os.system('cls')
global Enemy
print ("Player Name:",Player.name)
print ("Who would you like to fight?")
print ("1.)Steve")
print ("2.)Barry")
print ("3.)Change your name")
option = input("==>")
if option == "1":
Enemy = Steve("Steve", 100, 200, 10, 20, 30, 50)
fight()
elif option == "2":
Enemy = Barry("Barry", 100, 200, 10, 20, 30, 50)
fight()
elif option == "3":
nameSelection()
def attack():
Enemy.hp -= Player.strength
def fight():
os.system('cls')
while Enemy.hp > 0:
os.system('cls')
print(CharacterStats())
print ("1.) Attack")
print ("2.) Run")
option = input("==>")
if option == "1":
attack()
print (Enemy.hp)
print ("You did it! You have defeated", Enemy.name,"!")
gameStart()
def CharacterStats():
print ("You now face", Enemy.name)
print ("His current health is", Enemy.hp,"/",Enemy.maxhp)
print ("His strength is", Enemy.strength)
print ("His intelligence is", Enemy.intel)
print ("His charm is", Enemy.charm)
print ("He is level", Enemy.level)
Start()
When I get to a fight encoutner with one of the two options, I get
You now face Steve
His current health is 100 / 200
His strength is 10
His intelligence is 20
His charm is 30
He is level 50
None
1.) Attack
2.) Run
==>
I have read that return could fix it, but I can't seem to get return to give me the desired results I was looking for, both how it looks different went printed in to the player, and it only returns one of these lines of stats. I may be getting some of my terms wrong, I hope I am being clear on what my issue is.

You are getting None because you are printing the function, where you should just call the function, your function doesn't return anything and that is why you are getting None.
Change this line:
print(CharacterStats())
to:
CharacterStats()

In Python, when you call a function, that function does its work and then returns a value. For instance,
def add(x, y):
print("Working on it...")
answer = x + y
print("Got it!")
return answer
When called, this function will do four things. It will print "Working on it..." to the terminal. It will create a variable called answer, and assign it to the sum of x and y. It will print "Got it". And then, it will silently return that answer.
What does return mean? It means two things: it tells Python to return control to the place where the function was called, and it also says: wherever I was called, replace me with a certain value.
So if I write
print(add(2,3))
the function will be called and do its thinking, printing "working" and "got it" to the terminal. It will return 5, so now Python comes back to the print call and replaces add(2, 3) with 5:
print(5)
which will print 5. Similarly, I could do:
x = add(4,6) + add(5,2)
This would print:
Working on it...
Got it!
Working on it...
Got it!
And then x would be set to 10 + 7, or 17.
In your code, since you don't explicitly return anything from your function, Python uses the default, implicit return of None when it reaches the last line of your function. That means that
print(MyFunc())
actually is understood as, do the function, then
print(None)
Hope that clears things up!

As a side note, it will be more suitable if you use inheritance (use the Player class as base class eg: class Steve (Player):pass ) in your game : https://docs.python.org/2/tutorial/classes.html

How to call variable from one function in another file inside a function in another file?

I can't really copy over all of the code in both of these files since it is over 1000 lines, but essentially I am making a program that has the variables 'strength', 'endurance', 'strength', 'dexterity', 'intelligence', 'wisdom', and 'luck' (it's an rpg game) and I am trying to get the variable 'damage', which is an equation of 'strength' * 'dexterity' / 100, into another file. All of these variables are within the function character() in a file specifically for creating your character, and I'm trying to call over these variables again in another file for the main game, inside a variable called fight(). I've tried a multitude of things such as global variables, and using return, but nothing has worked for me. I'm sorry if I explained that poorly, comment if you have any questions.
The code in question.
character.py
def character():
#tons of stuff go here
global damage
damage = strength * dexterity / 100
game.py
def fight():
choice = input('(Type in the corresponding number to choose.) ')
global enemy_health
global damage
if choice == 1:
print ' '
print enemy_health,
enemy_health += -damage
print '-->', enemy_health
Thank you for your time.

I guess you could try importing character.py to game.py.
game.py: (edited)
import character
character_health = character.health
character_strength = character.strength
def fight():
...
But yeah, use classes.
Edit: example class
game.py:
class Character(object):
def __init__(self, health, strength):
self.health = health
self.strength = strength
self.alive = True
def check_dead(self):
self.alive = not(self.health)
def fight(self, enemy):
self.health -= enemy.strength
enemy.health -= self.strength
self.check_dead()
enemy.check_dead()
if __name__ == "__main__":
player = Character(300, 10) # health = 300, strength = 10
enemy = Character(50, 5) # health = 50, strength = 5
player.fight(enemy)
print("Player's health: {}\nIs he alive? {}\nEnemy's health: {}\nIs he alive? {}".format(player.health, player.alive, enemy.health, enemy.alive))

Passing on the parameters of a function into another one?

I'm not really sure how to word this, but I'll try my best. I've created a function for a zombie, and another one for attacks. But I don't know how to pass on the parameters of the zombie function into the attack function. Also if there is a more technical way to word this please let me know. Here is my test code for it, I'm sure this community will be able to figure out what I mean. The end goal is to create a function where I can plug in a monster name and have it's assigned parameters (health, defense, etc..) be run in through the combat function. ie def combat(monster_name): Any and all advice is much appreciated. Thank you!
#Functions
def zombie():
global zombie_hp
zombie_hp = 10
print "Zombie encounter"
print "Current Health:", zombie_hp
def attack(monster):
if monster > 0:
while monster > 0:
user_action = raw_input("Do you attack the zombie? [y]: ")
if user_action == "y":
monster_hp = monster_hp - 1
print "Health remaining: ", monster_hp
def user_action():
global user_action
user_action = raw_input("Do you attack the zombie? [y]: ")
# Zombie Encounter (attack_testing)
attack(zombie())
if zombie_hp == 0:
print "Zombie Defeated"

I suggest you use a class:
class Zombie:
def __init__(self):
self.defense = 10
self.hp = 100
def hit(self, hp):
self.hp-=hp
def upgrade(self, level):
self.defense+=level
This will remember the hp and defense for every zombie that you create
>>> Max = Zombie()
>>> Max.hit(17)
>>> Max.upgrade(2)
>>> Max.hp
83
>>> Max.defense
12
>>>
