递归取款和存款

Question

所以我刚刚开始研究这个以练习我的递归经验。我在这里有我的代码，出于某种原因，它只允许我使用其中的提款部分，而不是存款：

def recursive(n):
    print("You have $", n, "In the bank!")
    option = (input("Do you want to withdraw or deposit?"))    
    if option == "withdraw" or "Withdraw":
        withdraw = int(input("How much do you want to withdraw from your account?"))
        recursive(n - withdraw)

    elif option == "deposit" or "Deposit":
        deposit = int(input("How much do you want to deposit?"))
        recursive(n + deposit)

    else:
        print("Not a valid option!")
        print("Shutting Down!")

def money(n):
    if n < 0:
        print("You are out of money!")

def main():
    recursive(100)

main()

请在这里告诉我我的错误！

Answer 1

你应该改变：

if option == "withdraw" or "Withdraw":

到：

if option == "withdraw" or option == "Withdraw":

对deposit 也一样。
