from forex_python.converter import CurrencyRates # 创建 CurrencyRates 对象 c = CurrencyRates() # 循环转换货币 while True: # 输入金额和货币类型 amount = float(input("请输入金额：")) from_currency = input("请输入原货币类型：").upper() to_currency = input("请输入目标货币类型：").upper() # 转换货币 try: converted_amount = c.convert(from_currency, to_currency, amount) print(f"{amount} {from_currency} = {converted_amount} {to_currency}") except: print("货币转换失败！") # 询问是否继续转换 choice = input("是否继续转换？（Y/N）") if choice.lower() != "y": break 改长这个代码

以下是修改后的代码：

from forex_python.converter import CurrencyRates

def currency_converter():
    # 创建 CurrencyRates 对象
    c = CurrencyRates()
    
    while True:
        # 输入金额和货币类型
        amount = float(input("请输入金额："))
        from_currency = input("请输入原货币类型：").upper()
        to_currency = input("请输入目标货币类型：").upper()
        
        # 转换货币
        try:
            converted_amount = c.convert(from_currency, to_currency, amount)
            print(f"{amount} {from_currency} = {converted_amount} {to_currency}")
        except:
            print("货币转换失败！")
        
        # 询问是否继续转换
        choice = input("是否继续转换？（Y/N）")
        if choice.lower() != "y":
            break

这里将原来的代码封装在一个函数 `currency_converter()` 中，使得代码更加整洁和易读。
