You can also use f-strings to format the interpolated values. To do that, you can use format specifiers that use the syntax defined in Python’s string format mini-language. For example, here’s how you can present numeric values using a currency format:...
= -1: in_money = eval(currency_str_value[0:-3]) # 使用lambda定义函数convert_currency2 = lambda x: x * exchange_rate # 调用lambda函数out_money = convert_currency2(in_money) print('转换后的金额是:{} {} '.format(out_money, string)) else: print('无法计算') Get_huilv(url, header...
