求贷款46万元，期限360期，年利率3.25%的等额本金每月还款数的程序

为了计算46万元贷款，期限360期，年利率3.25%的等额本金还款法下的每月还款金额，可以按照以下步骤编写一个简单的程序：

首先，我们需要知道等额本金还款法的基本公式：
每月还款额 = (总贷款本金 / 还款月份数) + (总贷款本金 * 月利率)

其中，月利率 = 年利率 / 12

下面是一个Python示例程序，用于计算每月还款额：

def calculate_monthly_payment(total_loan, loan_term_in_years, annual_interest_rate):
    total_loan_amount = total_loan
    loan_term_in_months = loan_term_in_years * 12
    monthly_interest_rate = annual_interest_rate / 12

    # 计算每月应还本金
    principal_per_month = total_loan_amount / loan_term_in_months

    # 初始剩余本金
    remaining_principal = total_loan_amount

    # 循环计算每月利息加本金
    for month in range(loan_term_in_months):
        interest = remaining_principal * monthly_interest_rate
        this_month_payment = principal_per_month + interest
        remaining_principal -= principal_per_month

        yield this_month_payment

# 使用函数并设置具体数值
total_loan = 460000
loan_term_years = 3
annual_interest_rate = 3.25 / 100  # 将百分比转换为小数形式

monthly_payments = calculate_monthly_payment(total_loan, loan_term_years, annual_interest_rate)
for i, payment in enumerate(monthly_payments, start=1):  # 显示前几期的还款额，实际应用中可能需要遍历所有期数
    print(f"第{i}个月的还款额: {payment:.2f}元")
