日汇率人民币换算器

以下是一个简单的日汇率人民币换算器的示例代码，它使用假设的汇率进行计算。请注意，实际应用中应该使用实时汇率数据。

```python

class RMBExchangeRateCalculator:

def __init__(self, exchange_rates):

self.exchange_rates = exchange_rates

def convert_to_rmb(self, amount, currency):

if currency in self.exchange_rates:

return amount / self.exchange_rates[currency]

else:

raise ValueError("Unsupported currency")

def convert_from_rmb(self, amount, currency):

if currency in self.exchange_rates:

return amount self.exchange_rates[currency]

else:

raise ValueError("Unsupported currency")

假设的汇率数据，1美元兑换6.5人民币，1欧元兑换7.8人民币

exchange_rates = {

'USD': 6.5,

'EUR': 7.8
