Python looks procedural, however since the new object model was introduced in 2.2 with the original approach removed in 3.0, that it is OOP to its bones, even when people don't realize it.
It is, but it still has really good ergonomics for a procedural-first development style, and in many respects that still feels more natural in Python than a fully object-oriented style.
By contrast, Smalltalk is so deeply object-oriented that it doesn't technically even have an if statement, just instance methods in the boolean class.
And the vast majority of the time, we just pretend it's a weird syntax if-statement.
The practical importance is that we use the same tools to search for implementers and senders of #ifTrue: as we use to search for implementers and senders of any other method. (We use the same pencil to sketch that we use to write.)
