This is an exercise do help us practice using functions in Python. We’ll start by breaking the program into smaller sections and work on them one at a time.
We’ll define three functions: spin_row(), print_row() and get_payout(). Read through this code and ensure you fully understand what each function does and how it is working.
You can get built in emoji’s:
Annoyingly, this platform cannot display emoji’s correctly – they should look like those below, but instead I’ve had to use ASCII characters:
# Python Slot Machine
import random
def spin_row():
symbols = ['@', '#', '$', '%', '^']
return [random.choice(symbols) for _ in range(3)]
def print_row(row):
print("**************")
print(" | ".join(row))
print("**************")
def get_payout(row, bet):
if row[0] == row[1] == row[2]:
if row[0] == '@':
return bet * 3
elif row[0] == '#':
return bet * 4
elif row[0] == '$':
return bet * 5
elif row[0] == '%':
return bet * 10
elif row[0] == '^':
return bet * 20
return 0
def main():
balance = 100
print("*************************")
print("Welcome to Python Slots ")
print("Symbols: @ # $ % ^")
print("*************************")
while balance > 0:
print(f"Current balance: ${balance}")
bet = input("Place your bet amount: ")
if not bet.isdigit():
print("Please enter a valid number")
continue
bet = int(bet)
if bet > balance:
print("Insufficient funds")
continue
if bet <= 0:
print("Bet must be greater than 0")
continue
balance -= bet
row = spin_row()
print("Spinning...\n")
print_row(row)
payout = get_payout(row, bet)
if payout > 0:
print(f"You won ${payout}")
else:
print("Sorry you lost this round")
balance += payout
play_again = input("Do you want to spin again? (Y/N): ").upper()
if play_again != 'Y':
break
print("*******************************************")
print(f"Game over! Your final balance is ${balance}")
print("*******************************************")
if __name__ == '__main__':
main()
