Hello! I’ve run into an error in this project and I cant seem to figure out of to make it work. I was wondering if any of you could help me. Whenever I run this function, it gives me an error saying that the ‘money’ variable was referenced before assignment. Here is the code I wrote:

import random

money = 100

#Write your game of chance functions here
def coin_flip(guess, bet):
Heads = random.randint(1,1000)
Tails = random.randint(1,1000)
win = “Not Defined”
if Heads > Tails:
win = “Heads”

elif Heads < Tails:
win = “Tails”

if guess == win:
money += bet
msg = “You win $” + str(bet) + “!”
return msg

elif guess != win:
money = money - bet
msg1 = “You lost $” + str(bet) + “! Sorry!”
return msg1

#Call your game of chance functions here
print(coin_flip(“Tails”, 100))

Thanks for all the help! I really appreciate it!

I’m not sure, I’m fairly new to this myself… The only difference I see is during a ‘win’, you used the the += operator to change the value of money, whereas during the a ‘loss’, you used money = money - bet

Or maybe you need to return the value of money from the function? So it goes back to the global value?

Oh! good idea! I’ll try that and report back!

Hmm, even after I added return money it still pulled up the same error. I think theres a way to make a variable inside a function “Global” so i can use it outside the variable. Maybe i try that?

I added a code inside the function that goes like this:

global money

and now it works! Thanks for the help! :smiley:

awesome!!! not a problem!! I think you could also do something like have your function return the amount that a player bet… (negative if they lost)

and then call your function like this:

money += function()

Wow! Thats a pretty good idea! I’ll try that out next time I run into a problem like this! Again, thanks so much!
