HonFu but how we connect with him?

Answer 2

When you unpack a generator to a variable (what you do first with your variable 'd') you create a list (however you cannot 'append' anything to a tupple wich is imutable).

When you append something to a list, you add an item to the end of the actual targeted list... so the list is always a list ^^

When you unpack arguments, python engine know you're another context, and specification have defined that arguments are passed as tuple (because it's logical: there's no need to have a mutable list here).

Answer 3

visph i understood thank you😊
You are guru sir😇

Answer 4

I doubt there's a deeper meaning. It's probably just how it was defined.

str.split gives list, str.partition gives tuple.

Why? We'll probably have to ask Guido.

Answer 5

Guido is the Python creator / guru ;(
