python - Asking for user input while the program keeps running?

Question

Creating an automated battle system, but I want the user to have some input. The problem is whenever I ask for input the entire function stops until it gets input from the user.

def EnemyAttack(TypeOfEnemy):
global raceinput
special_ability_prompt = input("") #When you make the magic classes and put them in a dictionary, append them here.
while (Player.hp > 1 and TypeOfEnemy.hp > 1):
    if (special_ability_prompt == "HeavyAttack()"):
        if (raceinput == "CAVE"):
            TypeOfEnemy.hp = TypeOfEnemy.hp - (Player.atk / 2)
            print("You use a Heavy Attack! The ",TypeOfEnemy.name," takes ",(Player.atk / 2), " damage!")
            time.sleep(Player.atkrate * 1.5)
        else:
            TypeOfEnemy.hp = TypeOfEnemy.hp - (Player.atk / 5)
            print("You use a Heavy Attack! The ",TypeOfEnemy.name," takes ",(Player.atk / 2), " damage!")
            time.sleep(Player.atkrate * 3)

If you look at the while loop, I ask for the player input there. The problem is, of course, the entire program stops to get the userInput instead of continuing with the program. I've tried putting that line in a while loop like this

While True:
    special_ability_prompt = input("")

I thought that this would somehow create another line in the program that the user can type in any command they want while the battle is going on live. The effect was that my function was just stuck on this while loop which was stuck on true... If anyone here on this forum knows how to achieve an effect like this let me know. All the code that is necessary to reproduce this problem is down below (removed some parts of the code which was not needed for the issue) Let me know if you need any clarification. Thanks!

我相信您必须使用线程才能运行单独的进程，同时还要进行用户交互。

您可以在此处阅读 python 中的线程（特别是 Python 3 中的线程模块）：https ://docs.python.org/3/library/threading.html
