要实现一个日元牌价计算器,我们可以使用一个在线汇率API来获取实时汇率,然后根据输入的金额进行转换。以下是一个简单的示例,使用Python语言和`requests`库来调用一个假设的汇率API,并计算日元转换成其他货币的金额。
你需要安装`requests`库,但根据你的要求,我不会在这里使用`pip`安装它。
以下是实现这一功能的代码:
```python
import requests
假设的汇率API URL
HOUR_RATE_API_URL = "https://api.exchangerate-api.com/v4/latest/JPY"
def get_exchange_rate():
response = requests.get(HOUR_RATE_API_URL)
if response.status_code == 200:
data = response.json()
return data['rates']
else:
print("Failed to fetch exchange rates.")
return None
def convert_yen_to_other_currency(yen_amount, currency_code):
exchange_rates = get_exchange_rate()
if exchange_rates and currency_code in exchange_rates:
rate = exchange_rates[currency_code]
converted_amount = yen_amount rate
return converted_amount
else:
print("Currency code not found or unable to fetch exchange rates.")
return None
示例:将10000日元转换成美元
yen_amount = 10000
currency_code = 'USD'
converted_amount = convert_yen_to_other_currency(yen_amount, currency_code)
if converted_amount is not None:
print(f"{yen_amount
