我正在为水果机编写代码，该代码以随机方式选择符号，并且无法找出我要去哪里。这是代码：
import random
credit = 100
def roll(credit):
sym1 = random.choice(symbols)
sym2 = random.choice(symbols)
sym3 = random.choice(symbols)
print("---Symbols---")
print(sym1, sym2, sym3, "\n")
if (sym1 == sym2 or sym1 == sym3 or sym2 == sym3) and not(sym1 == sym2 == sym3):
print("Winner! +50p")
credit += 50
return credit
elif (sym1 == sym2 == sym3) and sym1 != "Bell":
print("Winner! +£1")
credit = credit + 100
return credit
elif (sym1 == sym2 == sym3) and (sym1 == "Bell"):
print("Jackpot! +£5")
credit = credit + 500
return credit
elif (sym1 == sym2 == "Skull" or sym1 == sym3 == "Skull" or sym2 == sym3 == "Skull") and not(sym1 == sym2 == sym3):
print("Two Skulls! -£1")
credit = credit - 100
return credit
elif (sym1 == sym2 == sym3) and sym1 == "Skull":
print("Three Skulls! Lose all credit")
credit = 0
return credit
else:
print("Loser!")
symbols = ["Cherry", "Bell", "Lemon", "Orange", "Star", "Skull"]
print("You have", credit, "p", "\n")
while True:
print("")
play = input("Roll costs 20p. Would you like to roll? yes/no: ")
print("")
if play == "yes" or "y" or "Yes" or "Y":
if credit >= 20:
roll(credit)
credit -= 20
print("Credit is", credit, "p")
else:
print("You do not have enough money to roll!")
这里的问题是，当一个人获胜时，积分不会添加到积分变量中。但是20p总是被拿走。我会很感激这里的一些帮助。
谢谢
最佳答案
也：
在else函数的roll子句中添加return语句，否则游戏在第一次失败后就结束了，因为您会得到TypeError: unsupported operand type(s) for -=: 'NoneType' and 'int'。
在else循环的while子句中添加break语句-否则，您必须在回答“否”后手动停止代码。
完整的代码，以及Farhan和Chris_Rands的建议如下所示：
def roll(credit):
sym1 = random.choice(symbols)
sym2 = random.choice(symbols)
sym3 = random.choice(symbols)
print("---Symbols---")
print(sym1, sym2, sym3, "\n")
if (sym1 == sym2 or sym1 == sym3 or sym2 == sym3) and not(sym1 == sym2 == sym3):
print("Winner! +50p")
credit += 50
return credit
elif (sym1 == sym2 == sym3) and sym1 != "Bell":
print("Winner! +£1")
credit = credit + 100
return credit
elif (sym1 == sym2 == sym3) and (sym1 == "Bell"):
print("Jackpot! +£5")
credit = credit + 500
return credit
elif (sym1 == sym2 == "Skull" or sym1 == sym3 == "Skull" or sym2 == sym3 == "Skull") and not(sym1 == sym2 == sym3):
print("Two Skulls! -£1")
credit = credit - 100
return credit
elif (sym1 == sym2 == sym3) and sym1 == "Skull":
print("Three Skulls! Lose all credit")
credit = 0
return credit
else:
print("Loser!")
return credit
symbols = ["Cherry", "Bell", "Lemon", "Orange", "Star", "Skull"]
print("You have", credit, "p", "\n")
while True:
print("")
play = input("Roll costs 20p. Would you like to roll? yes/no: ")
print("")
if play in {"yes","y","Yes","Y"}:
if credit >= 20:
credit = roll(credit)
credit -= 20
print("Credit is", credit, "p")
else:
print("You do not have enough money to roll!")
break
