I'm trying to make a code so when the player attacks the enemy, the enemy's health goes down and doesn't reset

I'm new to coding and was struggling to make it so that when the player attacks the enemy, it updates the enemies health and the player is able to attack again until the health of the enemy is 0.
Ive come up with this but every time I make a second attack the goblins health goes back to 100 and goes from there.
For example, if I do a "basic attack" it does 100-20 = 80, but when I attack again, lets say another "basic attack" it displays 80 again instead of 60.
def combat_enemy_goblin():
small_goblin_health = 100
attack_basic = 20
attack_special = 50
attack_ultimate = 100
print("You are now in combat with a small goblin!")
print("")
print("")
print("Small Goblin: ", small_goblin_health, "Health Points")
while True:
try:
users_attack = int(input("""
Your Moves
----------------------------
1 - Basic attack [20]
2 - Special attack [50]
3 - Ultimate attack [100]
4 - Run [repeating action]
----------------------------

if users_attack == 1:
print("")
print("You use your basic attack")
print("")
print("The goblin has taken some damage")
print("")
print("Small Goblin: ", small_goblin_health - 20, "Health points")
print("")
else:
if users_attack == 2:
print("")
print("You use your basic attack")
print("")
print("The goblin has taken some damage")
print("")
print("Small Goblin: ", small_goblin_health - 50, "Health points")
print("")
else:
if users_attack == 3:
print("")
print("You use your basic attack")
print("")
print("The goblin has taken some damage")
print("")
print("Small Goblin: ", small_goblin_health - 100, "Health points")
print("")
else:
if users_attack == 4:
print("")
print(" You tried to run away but failed!")
except:
print("")
print("You cant do that!")
print("")
combat_enemy_goblin()

Your problem in code is you are only subtracting value from goblin health but not changing it.
I have written a comment where I change the code.
-= in code means that you are removing the value from a variable and assigning it to the result.
num = 10
print(num) # Output: 10
num-=1
print(num) # Output: 9
One more change in your code is you do not exit the program even if the goblin health is 0 or less I am adding this in the below code.
small_goblin_health = 100
attack_basic = 20
attack_special = 50
attack_ultimate = 100
print("You are now in combat with a small goblin!")
print("")
print("")
print("Small Goblin: ", small_goblin_health, "Health Points")
while True:
if small_goblin_health<=0: # edited
break # exit the loop if small_goblin_health is less than or equal to 0.
try:
users_attack = int(input("""

----------------------------
1 - Basic attack [20]

if users_attack == 1:
small_goblin_health-=20 #edited
print("")
print("You use your basic attack")
print("")
print("The goblin has taken some damage")
print("")
print("Small Goblin: ", small_goblin_health, "Health points")
print("")
elif users_attack == 2:

print("")
elif users_attack == 4:
print("")
print(" You tried to run away but failed!")
except ValueError: # edited

print("")

In hope this helps

How can I short this code with class and object

I am making an investment game in which the Gold and Bitcoin prices go down and up day by day but here I am getting a problem how can I make this code easy so I can add any other crypto and share with just 2-3 lines of code but now I have to code whole if-else statement to do this
Can I use Classes and objects but how

User/Player Health is not saved during attack simulation using a coin and random

I am a novice to python. My longterm project is to design a choose your own adventure text-based game.
A major component of this game is attack scenarios. With that in mind, I have been constructing a python program for simulating an attack scenario. In this case, by flipping a coin to first determine whether the player or the enemy attacks first. Afterwards, a random integer between 1 and 10 is used as the attack damage. A function (HealthCheck), checks the health of the player/enemy to determine whether the player/enemy is dead.
My main problem is that the enemy's and player's health restarts after an attack. How can my program save the user's health after an attack, instead of resetting to 10 HP?
Below is my python code. Thank you for your help.
import random
import time
import sys
enemyHealth = 10
playerHealth = 10
def playerAttack(enemyHealth):
attack_damage = random.randint(1, 10)
print("The player does " + str(attack_damage) + " damage points to
the enemy.")
enemyHealth -= attack_damage
print("The enemy has " + str(enemyHealth) + " HP left!")
enemyHealthCheck(enemyHealth)
pass
def enemyAttack(playerHealth):
attack_damage = random.randint(1, 10)
print("The enemy does " + str(attack_damage) + " damage points to
the player.")
playerHealth -= attack_damage
print("The player has " + str(playerHealth) + " HP left!")
playerHealthCheck(playerHealth)
pass
def turnChoice():
h = 1
t = 2
coin = ""
while coin != "h" and coin != "t":
coin = input("Player, flip a coin to decide who attack first.\n"
"Heads or tails? H for heads. T for tails.\n")
if coin == "h":
print("You chose heads.\n"
"Flip the coin. \n"
". . .")
time.sleep(2)
else:
print("You chose tails.\n"
"Flip the coin. \n"
". . .")
time.sleep(2)
choice = random.randint(1, 2)
if choice == coin:
print("Great choice. You go first.")
playerAttack(enemyHealth)
else:

if playAgain == "y":
print("You chose to play again.")
print(".")
print(".")
print(".")
time.sleep(2)
turnChoice()
else:
print("Game over. See you soon.")
sys.exit()
def playerHealthCheck(playerHealth):
if playerHealth <=0:
print("Player is dead. Game over.")
replay()
else:
print("The player has " + str(playerHealth) + " HP points!")
print("It is your turn to attack.")
playerAttack(enemyHealth)
def enemyHealthCheck(enemyHealth):
if enemyHealth <=0:
print("Enemy is dead. You win.")

else:
print("Enemy is not dead. The enemy has " + str(enemyHealth) + " HP points.")
print("It is their turn to attack.")

turnChoice()

To make the code edit the variables you need to use globals. When you call the variable with the parentheses in the function they are only edited in the scope of that variable, but when you use globals they get edited for the whole program. Here is an example. Below is the code that is using globals:
import random
import time
import sys
enemyHealth = 10
playerHealth = 10
def playerAttack():
global enemyHealth
attack_damage = random.randint(1, 10)
print("The player does " + str(attack_damage) + " damage points to the enemy.")
enemyHealth -= attack_damage
print("The enemy has " + str(enemyHealth) + " HP left!")
enemyHealthCheck()
pass
def enemyAttack():
global playerHealth
attack_damage = random.randint(1, 10)
print("The enemy does " + str(attack_damage) + " damage points to the player.")
playerHealth -= attack_damage
print("The player has " + str(playerHealth) + " HP left!")
playerHealthCheck()
pass
def turnChoice():
h = 1
t = 2
coin = ""
while coin != "h" and coin != "t":
coin = input("Player, flip a coin to decide who attack first.\n"
"Heads or tails? H for heads. T for tails.\n")
if coin == "h":
print("You chose heads.\n"
"Flip the coin. \n"
". . .")
time.sleep(2)
else:
print("You chose tails.\n"
"Flip the coin. \n"
". . .")
time.sleep(2)
choice = random.randint(1, 2)
if choice == coin:
print("Great choice. You go first.")
playerAttack()
else:
print("Enemy goes first.")
enemyAttack()
def replay():
playAgain = ""
while playAgain != "y" and playAgain != "n":
playAgain = input("Do you want to play again? yes or no")
if playAgain == "y":
print("You chose to play again.")
print(".")
print(".")
print(".")
time.sleep(2)
turnChoice()
else:
print("Game over. See you soon.")
sys.exit()
def playerHealthCheck():
global playerHealth
if playerHealth <= 0:
print("Player is dead. Game over.")
replay()
else:
print("The player has " + str(playerHealth) + " HP points!")
print("It is your turn to attack.")
playerAttack()
def enemyHealthCheck():
global enemyHealth
if enemyHealth <= 0:
print("Enemy is dead. You win.")

Run-time error when setting the value of a variable in Python

I want to make an RPG game, and I'm trying to make a system of buying items and potions. What I intended was for the player to get 3 potions of each in the beginning, but you need to buy more to continue with them. My problem is that they keep on resetting every time I call the fight function.
I've tried making them global in the beginning and defining them, but they keep on saying "Referenced before assignment"

I expect the potions to go to three when the player goes into battle in the first time, but afterwards when going to battle the amount of potions resets the the amount remaining from last battle.

Outside this Fight() function initialize your potion counts to 3 each. Then pass the current amount of potions in to the Fight() function something like: Fight(monster,Hpots,Wpots) then return the remaining potions to the outer scope with a return(HealPotionsLeft,WeakPotionsLeft)

Then assign the new values to potions:
CurrentHealPotions = BattleResults[1]
CurrentWeakPotions = BattleResults[2]

How come my ork fight stops and doesn't go to the move() command :/

At some parts of my code its just stop and doesn't go back to the move(). I want it to add the score and i did that with score = score + 100 BUT it just disrupts the code ;-;. Its a bit messy and i'm sorry about that but please help I have NO clue why it does this. Fyi I'm using this code on pythonroom if that helps.

You're trying to assign to global variable score within function end like this:
val = 5
def func():
val += 5
It won't work and will result to UnboundLocalError. In order to fix the issue just use keyword global:
val = 5
def func():
global val
val += 5
