Here's a deceptively fuzzy #Python term: mutable object. 🤔
mutable object: an object whose "value" can change
But what does "value" really mean?

Lists are mutable because a list object can be changed.
>>> numbers = [2, 1, 3]
>>> numbers.append(4)
>>> numbers
[2, 1, 3, 4]
If two variables refer to the same list, any change to the list will be reflected by both variables:
>>> x = numbers
>>> x.clear()
>>> numbers
[]
>>> numbers = [2, 1, 3]
>>> numbers.append(4)
>>> numbers
[2, 1, 3, 4]

Strings are immutable in #Python. That means that there is no way to "change" a string object in Python.
Try as hard as you might, you cannot change strings. You can only make NEW strings.
name = "Trey"
name = name + "!" # makes a new string
name += "!" # same as above
