What is the autocomplete source that shows with an "ID" icon?

[vinoff]

If I have an empty python file, say, test.py, and I type "for", I see many auto-complete options, the first of which has an "ID" icon. What is the source for that? I want to penalize it, I want snippets to show first.

I think it's for keywords. There is a recipe about disabling them: https://cmp.saghen.dev/recipes.html#exclude-keywords-constants-from-autocomplete
