为什么元组列表不可调用？当我调用一个参数为元组列表的函数时，它会显示错误

Question

定义调用上述函数（来宾列表）的函数后。如果元组（不是列表）在同一行中，我如何打印元素

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

我需要以ken is 30 years old and he is a chef的形式输出

Answer 1

以下代码应按您的要求执行：

for guest in guest_list:
    name = guest[0]
    age = guest[1]
    job = guest[2]
    print(f"{name} is {age} years old and he is a {job}")

Answer 2

如果我理解正确，您需要编写guest_lists()函数来打印每个来宾的信息。在这种情况下，您可以迭代列表并打印每个条目的信息，如-

def guest_list(guests):
    for (name, age, profession) in guests:
        print("{} is {} years old and is a {}".format(name, age, profession))

Answer 3

试试这个：

def guest_list(guests):
    for guest in guests:
        print(f'{guest[0]} is {guest[1]} years old and he is {guest[2]}')
