房贷计算python代码

当然，我可以给你介绍一下房贷计算的Python代码。下面是一个简单的示例：

def calculate_loan(principal, interest_rate, years):
    monthly_interest_rate = interest_rate / 12 / 100
    months = years * 12
    monthly_payment = principal * monthly_interest_rate * (1 + monthly_interest_rate) ** months / ((1 + monthly_interest_rate) ** months - 1)
    total_payment = monthly_payment * months
    total_interest = total_payment - principal
    return monthly_payment, total_payment, total_interest

principal = float(input("请输入贷款本金（单位：万元）："))
interest_rate = float(input("请输入年利率（单位：%）："))
years = int(input("请输入贷款年限（单位：年）："))

monthly_payment, total_payment, total_interest = calculate_loan(principal, interest_rate, years)

print("每月还款金额为：%.2f 元" % monthly_payment)
print("总还款金额为：%.2f 元" % total_payment)
print("支付利息总额为：%.2f 元" % total_interest)

这段代码实现了房贷计算功能，用户需要输入贷款本金、年利率和贷款年限，然后计算出每月还款金额、总还款金额和支付利息总额。
