房贷计算器pycharm

以下是一个简单的房贷计算器的Python代码，可以在PyCharm中运行：

def payment_loan(amount, years, rate):
    # 计算每月还款额
    n = years * 12
    r = rate / 12
    payment = (amount * r * (1 + r) ** n) / ((1 + r) ** n - 1)
    # 计算还款总额和支付利息总额
    total_payment = payment * n
    total_interest = total_payment - amount
    # 将结果存储在字典中并返回
    result = {'Monthly payment': round(payment, 2),
              'Total payment': round(total_payment, 2),
              'Total interest': round(total_interest, 2)}
    return result


def calculate_loan():
    # 循环让用户选择贷款类型并输入相应的信息
    while True:
        loan_type = input('请选择贷款类型（1-商业贷款，2-公积金贷款）：')
        if loan_type == '1':
            amount = float(input('请输入贷款金额（单位：万元）：'))
            years = int(input('请输入贷款期限（单位：年）：'))
            rate = float(input('请输入贷款利率（单位：%）：')) / 100
            result = payment_loan(amount, years, rate)
            # 显示计算结果
            print('每月还款额：', result['Monthly payment'])
            print('还款总额：', result['Total payment'])
            print('支付利息总额：', result['Total interest'])
            break
        elif loan_type == '2':
            amount = float(input('请输入贷款金额（单位：万元）：'))
            years = int(input('请输入贷款期限（单位：年）：'))
            rate = float(input('请输入贷款利率（单位：%）：')) / 100
            result = payment_loan(amount, years, rate)
            # 显示计算结果
            print('每月还款额：', result['Monthly payment'])
            print('还款总额：', result['Total payment'])
            print('支付利息总额：', result['Total interest'])
            break
        else:
            print('输入有误，请重新输入。')
