函数 "pop" 返回错误。我正在尝试删除列表中的元素

Question

我正试图使用pop函数删除列表中的第四个元素。然而，我不断收到一条错误消息。请帮忙。

inventory = ["twin bed", "twin bed", "headboard", "queen bed", "king bed", "dresser",
"dresser", "table", "table", "nightstand", "nightstand", "king bed",
"king bed", "twin bed", "twin bed", "sheets", "sheets", "pillow",
"pillow"]
removed_item = inventory.pop[4]
print(removed_item)

这是不断返回的错误消息；

Traceback (most recent call last):
File "script.py", line 18, in <module>
removed_item = inventory.pop[4]
TypeError: 'builtin_function_or_method' object is not subscriptable

Answer 1

是的，你是对的，pop()确实有一个索引，但你不像pop[4]那样写，所以就像quamrana说的那样，你应该放inventory.pop(4)而不是inventory.pop[4]
