How to extend a list with iterable and non-iterable object in one line?

Lets say I have 3 objects:

object1 = [1, 2, 3]
object2 = 'string'
object3 = {'key': 10}

I am trying to create a new list object in one line such that it looks like this:

object4 = [1, 2, 3, 'string', {'key': 10}]

>Solution :

you can use unpacking for the iterables:

object4 = [*object1,object2,object3]
