Pylance doesn’t seem to know about the int.bit_count method

[Openstreetmapler]

Environment data

• Pylance version: unknown, shipped with the Microsoft VSCode Python extension, version 2024.22.0
  • Pylance doesn’t appear as a separate entry in my VSCodium extension manager.
• OS and version: Ubuntu 22.04
• Python version: Python 3.10.12 at path /bin/python3

Code Snippet

Type the following into VSCode/VSCodium:

number = 123
number.bit_count()

While typing the second line, the Python extension will suggest bit_length but not bit_count even though the latter function was added to the int class with Python 3.10.

Expected behavior

After typing number.bit_, both bit_count and bit_length are suggested as auto-completions.

Actual behavior

After typing number.bit_, only bit_length is suggested.

Logs

N/A – I don’t think this issue needs a log trace as it’s just a missing feature or oversight, in my opinion.

This does work but you have to select an interpreter that's 3.10 or higher:

The interpreter down here:

If say I pick a 3.9 interpreter, I get this:

This does work but you have to select an interpreter that's 3.10 or higher:

I have the choice between three interpreters which are all version 3.10.12. Therefore, please reopen the issue.

The issue also occurs on macOS 12.7.5. And yes, I’m also using Python 3.10 or higher in this case!

Can you include the log as described here?

https://github.com/microsoft/pylance-release/blob/main/TROUBLESHOOTING.md#filing-an-issue

That should tell us which version we think python is. It might be that the version you picked doesn't run for some reason and we can't get the version information from it.

No, I can’t. For me, "python.analysis.logLevel": "Trace" is displayed as Unknown Configuration Setting and there’s also no Pylance: Start Logging command available. I instead tried Developer: Set Log Level…, setting it to Trace, but this doesn’t print out useful info …

Wait a moment, I found this in the logs:

[info] Starting Jedi language server for [workspace folder].

As I prefer VSCodium over the faux-open-source VSCode, I’m actually using the Jedi language server, not Pylance.
Therefore, I’ll repost this issue on the Jedi repository. You can change the issue status to Not planned.
