以下是一个简单的韩币兑换人民币的实时汇率查询与换算工具。请注意，这个工具仅供参考，实际汇率可能会有所不同，具体以银行或官方汇率机构公布的实时汇率为准。
```python
import requests
def get_realtime_exchange_rate():
获取实时汇率API的URL
url = "https://api.exchangerate-api.com/v4/latest/KRW"
try:
发送HTTP请求获取汇率数据
response = requests.get(url)
response.raise_for_status() 检查请求是否成功
data = response.json()
krw_to_cny_rate = data['rates']['CNY']
return krw_to_cny_rate
except requests.RequestException as e:
print("请求汇率API时发生错误：", e)
return None
def convert_krw_to_cny(krw_amount):
krw_to_cny_rate = get_realtime_exchange_rate()
if krw_to_cny_rate is not None:
cny_amount = krw_amount krw_to_cny_rate
return cny_amount
else:
return None
示例：将1000韩币兑换成人民币
krw_amount = 1000
cny_amount = convert_krw_to_cny(krw_amount)
if cny_amount is not None:
print(f"{krw_amount
