This is dependent on a setting that tells the language server to automatically add closed brackets.

@rchiodo seems like someone got the same issue as mine. Btw, I still have this issue. https://github.com/microsoft/vscode-python/issues/6926 https://github.com/microsoft/vscode-python/issues/6471

[rchiodo]

Yes we found out yesterday this is a custom setting. We (the editor) are supposed replace the $0 with a cursor position

[DavidKutu]

@rchiodo @DonJayamanne I can't reproduce this. Can you try it?

[rchiodo]

I believe you need a custom setting for it to cause that. @StevenLi-DS can you share any settings you have set?

[stevenlis]

@rchiodo which settings?

[rchiodo]

The contents of your settings.json file. Example, this is what mine looks like:

}

But I don't repro you bug. We believe there's a setting for that '$0' you're getting.

[DavidKutu]

thank you @StevenLi-DS

[stevenlis]

Does this those icons mean anything?

[rchiodo]

Yes. About halfway down this page it explains what the icons mean: https://code.visualstudio.com/docs/editor/intellisense

[rchiodo]

Somebody else should validate this as both David and I made changes.

[IanMatthewHuff]

I've not reproed this myself. But I can validate that with the python.autoComplete.addBrackets setting on I don't get the $0 for autocomplete. Closing.

[ghost]

Is the update released already? I'm still having this problem.

[rchiodo]

This fix is in the insider's build, not the general release yet.
