“函數”對象不可迭代

Question

當我進入

guest_list = [('Ken', 30, "Chef"), ("Pat", 35, 'Lawyer'), ('Amanda', 25, "Engineer")]

for guests in guest_list:          #guests is a tuple
    
     res = "{} is {} years old and works as {}.".format(guests[0], guests[1], guests[2])
     print(res)

它工作正常但是當我將其更改為

def guest_list(guests):

    for guests in guest_list:

        res = "{} is {} years old and works as {}.".format(guests[0], guests[1], guests[2])
        print(res)
guest_list([('Ken', 30, "Chef"), ("Pat", 35, 'Lawyer'), ('Amanda', 25, "Engineer")]

我得到

TypeError: 'function' object is not iterable

有沒有人有什么建議？

謝謝，

Answer 1

您正在迭代函數名稱 guest_list 而不是列表名稱來賓。 guest_list 函數內部的代碼應該如下

for item in guests:
   #print item

Answer 2

改變：

def guest_list(guests):

到：

def show_guest_list(guest_list):

函數名稱與guest_list沖突。 並且參數需要是guest_list而不是guests 。

然后調用它：

show_guest_list([('Ken', 30, "Chef"), ("Pat", 35, 'Lawyer'), ('Amanda', 25, "Engineer")]
