要在给定的代码中加入复利计算,你需要更新`calculateMonthlyPayment`函数和相关的逻辑。以下是如何实现复利的一个例子:
```python
def calculateMonthlyPayment(principal, annualInterestRate, termInYears, isCompoundedAnnually):
monthlyInterestRate = annualInterestRate / 12
if isCompoundedAnnually:
# 如果按年计息,转换为每月的单利支付
monthlyPayment = principal * (monthlyInterestRate / (1 - (1 + monthlyInterestRate) ** (-termInYears * 12)))
else:
# 按月计息,采用复利公式
months_in_term = termInYears * 12
months_to_payment = termInYears * 12 - 1
numerator = (monthlyInterestRate * (1 + monthlyInterestRate) ** months_to_payment)
denominator = (1 + monthlyInterestRate) ** months_in_term - 1
monthlyPayment = principal * numerator / denominator
return round(monthlyPayment, 2)
# ...其他部分保持不变...
```
在这个版本里,我们考虑了两种情况:按年计息(简单利息)和按月计息(复利)。如果你需要让用户选择计息频率,你可以添加一个新的参数或者在调用函数时进行条件判断。这样,当你调用`calculateMonthlyPayment`时,传入`isCompoundedAnnually=False`即可启用复利计算。记得更新文档说明以解释这个新功能。
