Im getting a Index Error, when i tried to make a dummy console game with basic oop

Now i will give you more details, the game has max 10 min 6 players,they should randomly choose another player and attack them. So here in for loop i am tring to randomly choose who is gonna atack and who is going to get hurt, but it gives error

import random

class Fighter:
    def __init__(self, name, health, power, stamina):
        self.name = name
        self.health = health
        self.power = power
        self.stamina = stamina
        self.fighter_stats = [self.name, self.health, self.power, self.stamina]

    @classmethod
    def Get_Hurt(cls):
        pass

    @classmethod
    def Attack(cls):
        pass

fighters_list = []
atackers_list = []
dummy_value = 0
fighter_num = random.randint(6, 10)
atackers_num = random.randint(1, 6)

for i in range(1, fighter_num + 1):
    fighter_health = random.randint(55, 100)
    fighter_power = random.randint(20, 35)
    fighter_stamina = random.randint(3, 7)
    fighter = Fighter(f"fighter{i}", fighter_health, fighter_power, fighter_stamina)
    fighters_list.append(fighter.name)
    dummy_value += 1
    while True:    #this while loop is for making sure if the for loop is in its last loop  
        if dummy_value != fighter_num + 1:
            dummy_value += 1
            continue
        else:
            for i in range(atackers_num):
                rand_attacker = random.choice(fighters_list)
                atackers_list.append(rand_attacker)
                fighters_list.remove(rand_attacker)
            break

print(fighters_list)
print(atackers_list)

And that is the console output:

Traceback (most recent call last):
  File "C:\Users\azaz9\PycharmProjects\oyrenme\yoxlama.py", line 38, in <module>
    rand_attacker = random.choice(fighters_list)

    return seq[self._randbelow(len(seq))]
IndexError: list index out of range

You are appending only one fither, and then trying to get the attackers.
In this way after the first iteration the list is empty and the subsequent call to .choice() fails.

You should append all the fighters, than choose the attackers:

fighters_list = []
atackers_list = []
dummy_value = 0
fighter_num = random.randint(6, 10)
atackers_num = random.randint(1, 6)

for i in range(1, fighter_num + 1):
    fighter_health = random.randint(55, 100)
    fighter_power = random.randint(20, 35)
    fighter_stamina = random.randint(3, 7)
    fighter = Fighter(f"fighter{i}", fighter_health, fighter_power, fighter_stamina)
    fighters_list.append(fighter.name)
    dummy_value += 1
while True:    #this while loop is for making sure if the for loop is in its last loop  
    if dummy_value != fighter_num + 1:
        dummy_value += 1
        continue
    else:
        for i in range(atackers_num):
            print(len(fighters_list))
            rand_attacker = random.choice(fighters_list)
            atackers_list.append(rand_attacker)
            fighters_list.remove(rand_attacker)
        break

print(fighters_list)
print(atackers_list)

• your while loop is useless, that is just the following code

  dummy_value = fighter_num + 1
  
  for i in range(atackers_num):
      rand_attacker = random.choice(fighters_list)
      atackers_list.append(rand_attacker)
      fighters_list.remove(rand_attacker)
  

• the first for loop initializes the stuffs, the "while" loop (or just the main code) should be outside/after it

Resulting in

for i in range(1, fighter_num + 1):
    fighter_health = random.randint(55, 100)
    fighter_power = random.randint(20, 35)
    fighter_stamina = random.randint(3, 7)
    fighter = Fighter(f"fighter{i}", fighter_health, fighter_power, fighter_stamina)
    fighters_list.append(fighter.name)
    dummy_value += 1

dummy_value = fighter_num + 1

for i in range(atackers_num):
    rand_attacker = random.choice(fighters_list)
    atackers_list.append(rand_attacker)
    fighters_list.remove(rand_attacker)
