There is a function hex(number, /), and float objects have a method hex().
When something like 1.3.hex( is typed, the yellow box's first line contains hex(number, /). But the method is actually hex(), no arguments. It confuses users.
And when 1.3.list( is typed, there isn't a list() method in floats, but the hint still pops up and shows the __doc__ for list(iterable=(), /).
