英文:
VSCode IntelliSense thinks a Python 'function()' class exists
问题
在这个情况下，VSCode / IntelliSense正在自动完成一个名为 function() 的Python类，但似乎该类并不存在。
例如，以下代码看起来是有效的：
def foo(value):
return function(value)
foo(0)
但是，在这个范围内未定义 function，因此运行时会引发 NameError：
Traceback (most recent call last):
File "/home/hayesall/wip.py", line 4, in <module>
foo(0)
File "/home/hayesall/wip.py", line 2, in foo
return function(value)
NameError: name 'function' is not defined
我期望 IntelliSense 能够警告我 function 未定义。function() 似乎没有文档字符串，我在更广泛的Python/CPython/VSCode文档中也找不到有关它的任何信息。 (附注: pylint 识别为 "Undefined variable 'function'")。
function() 是什么？或者：有关为什么 IntelliSense 匹配它的解释吗？

输入单词 function 时提供了自动完成：
function 在这个范围内未定义，但 IntelliSense 似乎认为它是定义的：

Python 3.9.15 (CPython, GCC 11.2.0)
英文:
VSCode / IntelliSense is completing a Python class called function() that does not appear to exist.
For example, this appears to be valid code:
def foo(value):
return function(value)
foo(0)
But function is not defined in this scope, so running this raises a NameError:
Traceback (most recent call last):
File "/home/hayesall/wip.py", line 4, in <module>
foo(0)
File "/home/hayesall/wip.py", line 2, in foo
return function(value)
NameError: name 'function' is not defined
I expected IntelliSense to warn me about function being undefined. function() does not appear to have a docstring, and I cannot find anything about it in the wider Python/CPython/VSCode documentation. (Side note: pylint recognizes "Undefined variable 'function'").
What is function()? Or: is there an explanation for why IntelliSense is matching this?

Writing the word function provides an autocomplete:
function is not defined in this scope, but IntelliSense seems to think that it is:

得分: 1
function 类型是函数的一种类型（在 Python 中，函数是对象），考虑到
def return_one():
return 1
print(type(return_one))
输出为
<class 'function'>
英文:
function class is type of function (functions are objects in python), consider that
def return_one():
return 1
print(type(return_one))
gives output
<class 'function'>
