python 3.9.2 windows argparse no module _typeshed

[Stargateur]

MCVE:

import argparse

Error:

Traceback (most recent call last):
  File "C:\Users\Star\git\optomata\options.py", line 1, in <module>
    from _typeshed import AnyPath
ModuleNotFoundError: No module named '_typeshed'

At this point I don't know what to do.

#5021 doesn't seem related

[Stargateur]

OK nevermind, visual studio code troll me

OK nevermind, visual studio code troll me

So, what was the solution?

[Stargateur]

none, I copy paste a code and somehow scroll and never saw the problem was on the first line. (on a 3 line file ??? as I said visual studio troll me I don't know how, it add the import line I think)

[manudut]

Yeah, happened exactly the same to me...

[Navneety007]

Yeah same here people

[Akuli]

Can we get more details about how this is happening? What editor and version? What is the name of the file you save the code into? Which button do you click in the editor to run it?

[BradMclain]

I had the same error and thought i was going mad for a second.

For those asking for more details visual studio code autocomplete had added the following at top of file and then scrolled down causing line 1 to be hidden. As @Stargateur indicates this even happens in very short files.

from _typeshed import OpenTextMode

Why this happened?
[answer]:

Hey, guys! This happens because inside the code there's some attribute being called when creating basic functions like

open(file="AnyPath", mode=OpenTextMode)

Notice that 'AnyPath' and 'OpenTextMode' aren't variables you created in your code, they are already built in to python and your code is importing them and, whenever we call something from outside our file.py, we must declare it by using

from module import object

What VSCode did was complete the code with those necessary commands for this attributes to work

And what those attributes do?
I haven't gone that far in my research but I suppose it compiles some "raw" parameter for the function open()

open(file/path/and/name, openingMode): #the openingMode defines the purpose of opening the file
open(myFile, "r") #means the file is open for read only privillege
open(myFile, "w") #means the file is open for write only privilleges
open(myFile, OpenTextMode) #probably means it's open with all privilleges

from typing import TYPE_CHECKING

if TYPE_CHECKING:
from _typeshed import ...

Use this work for me

python 3.9
Возникала ошибка:
from _typeshed import Self
ModuleNotFoundError: No module named '_typeshed'

Мне помог импорт:
import typing

[Mwatchorn26]

Same here, it automatically added the "from _typeshed import" statement at line 1.
I wonder - Is this a VS Code issue, or caused by an extension?
