這哪里錯了？，報錯： unsupported operand type(s) for +=: 'int' and 'tuple'（+=：“int”和“tuple”的操作數類型不受支持）
我自己寫的: def?average(*args): ????b?=?0 ????if?len(args)?==?0: ????????return?b ????else: ????????for?i?in?args: ????????????b?+=?i ????????avg?=?b?/?len(args) ????????return?avg a=(1,?2,?3,?4,?5) print(average(a))
參考答案：
def?average(*args): ????sum?=?0 ????if?len(args)?==?0: ????????return?sum ????for?item?in?args: ????????sum?+=?item ????avg?=?sum?/?len(args) ????return?avg a=(1,?2,?3,?4,?5) print(average(a))
