编写一个程序，处理储蓄账户的取钱问题。程序的输入是目前的账户余额和需要取款的数目，输出是取款后的账户余额。如果取款数大于账户余额，请输出“Withdrawal denied.”，如果取款后的账户余额小于$150，输出信息“Balance below $150”

你可以用下面的Python代码来实现这个功能：

def withdraw_funds(account_balance, withdrawal_amount):
    if withdrawal_amount > account_balance:
        return "Withdrawal denied."
    else:
        new_balance = account_balance - withdrawal_amount
        if new_balance < 150:
            return f"Balance below $150 after the withdrawal."
        else:
            return new_balance

# 示例用户输入
account_balance = float(input("请输入当前账户余额："))
withdrawal_amount = float(input("请输入需要取款的金额："))

result = withdraw_funds(account_balance, withdrawal_amount)
print(result)
