外汇兑换python

外汇兑换是指将一种货币兑换成另一种货币的过程。在Python中，可以使用第三方库来进行外汇兑换计算。常用的库包括`forex-python`和`ccy`等。

1. 使用`forex-python`库进行外汇兑换：

   from forex_python.converter import CurrencyRates

   c = CurrencyRates()
   amount = 100
   from_currency = 'USD'
   to_currency = 'CNY'
   converted_amount = c.convert(from_currency, to_currency, amount)
   print(f"{amount} {from_currency} = {converted_amount} {to_currency}")

2. 使用`ccy`库进行外汇兑换：

   from ccy import currency

   amount = 100
   from_currency = currency('USD')
   to_currency = currency('CNY')
   converted_amount = amount * to_currency / from_currency
   print(f"{amount} {from_currency} = {converted_amount} {to_currency}")

以上是两种常用的外汇兑换的Python实现方式。
