函数中的积分变量不起作用

Question

我正在尝试使第一个函数 opt1() 使健康下降 50 点，但是由于某种原因它不起作用。该代码在不在函数中时有效。不起作用的行： health = int(health) - 50

import random

health = "100"

p = "1"

def opt1():

   print("Du förlorade striden")

   health = int(health) - 50

   print(health)

def opt2():

   print("hej2")

def opt3():

   print("hej3")

q = [opt1, opt2, opt3]

ind = random.randint(0,len(q)-1)

print("you have ", p, " potions")

print("Your health is ", health,)

while True:

   print("Commands: Add, drink, sleep, fight, quest")

   a = input("Enter a command: ")

   if a == "add":

       health = int(health)

       p = int(p) + 1

       print("you have ", p, " potions")

       print("Your health is ", health,)

   if a == "fight":

       q[ind]()

Answer 1

def opt1():在 opt1 中，您应该声明您提供给函数的变量。例如：def opt1(health):
