Python实现简单的货币兑换程序

import requests

def currency_converter(amount, from_currency, to_currency):

    # 使用API获取汇率数据

    url = f"https://api.exchangerate-api.com/v4/latest/{from_currency}"

    response = requests.get(url)

    data = response.json()

    # 计算兑换后的金额

    exchange_rate = data['rates'][to_currency]

    converted_amount = amount * exchange_rate

    return converted_amount

# 使用例子

amount = 100

from_currency = 'USD'

to_currency = 'CNY'

converted_amount = currency_converter(amount, from_currency, to_currency)

print(f"{amount} {from_currency} 兑换成 {converted_amount} {to_currency}")
