法国汇率换算器

以下是一个简单的法国汇率换算器的示例代码，使用Python编写。此代码使用了固定汇率进行换算，实际应用中您可能需要根据实时汇率进行更新。

```python

class FranceExchangeRateCalculator:

def __init__(self, exchange_rate):

self.exchange_rate = exchange_rate

def convert_to_euros(self, amount, currency):

if currency == "USD":

return amount / self.exchange_rate

elif currency == "GBP":

return amount 1.18 / self.exchange_rate

elif currency == "JPY":

return amount 0.0091 / self.exchange_rate

else:

return "Unsupported currency"

def convert_from_euros(self, amount, currency):

if currency == "USD":

return amount self.exchange_rate

elif currency == "GBP":

return amount self.exchange_rate / 1.18

elif currency == "JPY":

return amount self.exchange_rate 0.0091

else:

return "Unsupported currency"

示例用法

if __name__ == "__main__":

假设当前汇率为1欧元兑换1.18美元

exchange_rate_calculator = FranceExchangeRateCalculator(exchange_rate=1.18)

将100美元换算成欧元

amount_in_usd = 100

amount_in_euros = exchange_rate_calculator.convert_to_euros(amount_in_usd, "USD")

print(f"{amount_in_usd
