Consider the following class definition:

class

def

Stack$($list$)$ :

push $($self$,$

item$)$ :

self. append $($item$)$

What is the downside of this implementation approach?

Not all of the required Stack operations are defined.

It's unnecessary because Python has a built$-$in Stack data structure you can use.

You are exposing all list methods, not just the push $($append$)$ and pop.

It would have been better to inherit from a different built$-$in data structure.
