Python中的利息计算器。找出总金额和每年要支付的金额

def calculate_interest(principal, rate, years):
    total_amount = principal * (1 + rate/100)**years
    annual_payment = total_amount / years
    return total_amount, annual_payment

principal = float(input("请输入本金金额："))
rate = float(input("请输入年利率（百分比）："))
years = int(input("请输入贷款或投资的年限："))

total_amount, annual_payment = calculate_interest(principal, rate, years)

print("总金额为：", total_amount)
print("每年要支付的金额为：", annual_payment)
