Ditto - reading is more important than writing, and starting with the operation means earlier comprehension of the operation. Also typing-aware autocomplete can notice when you type "await' and prefer autocompleting async methods, though I'm not sure any autocompletion engines have this feature (yet). I'm using TabNine with the Python language server ( https://github.com/palantir/python-language-server ) and this uses at least some typing information to power its autocompletion.
