Hello, thanks for reaching out. Your request may be duplicated of #1340 so we're gonna close it. You can find our answer on that link!

Vira Icons has a system that manages icon accents, folder styles, and icon associations. The icons are hand-curated one by one to ensure consistency and add meaning to them (so the UI doesn’t get cluttered with unnecessary icons). For these reasons we don’t currently have a system to let users manually associate icons with folders or files, we’d be more than happy to add any missing icons that could be helpful for Python developers. We don’t know every stack’s tools, so we’re open to suggestions!

Please feel free to submit any icon request for folders and files you miss by using the appropriate section so we can track the requests. Some of the folder icons in your screenshot have been added and will be available next release.
