List Methods in Python on Exercism
Lists support both common and mutable sequence operations such as min(<list>)/max(<list>), <list>.index(), <list>.append() and <list>.reverse(). Items can be iterated over using the for item in <list> construct, and for index, item in enumerate(<list>) when both the element and element index are needed. Python provides many useful methods for working with lists.

October 19, 2019List of all Python dunder methods?
Sounds like a classic case of X-Y-problem. What are you trying to achieve?
I don't think trying to maintain a comprehensive list of dunder methods is a good idea. Consider that this list is bound to change with upcoming versions of Python and has already undergone considerable changes in the past. You may end up maintaining varying lists of magic methods for different versions of Python.
I think the goto approach here would be to just try to call the respective method from within a generic __getattribute__ and react appropriately to TypeError.
It may also be possible to analyse the proxied object's class dict (someobject.__class__.__dict__) to find out which dunder methods were defined on that class. Of course you may end up having to walk up the inheritance chain as well, so this is bound to get quite complicated.

March 6, 2018What is Python's list.append() method WORST Time Complexity? It can't be O(1), right?
I've read on Stackoverflow that in Python Array doubles in size when run of space It's actually not double, but it does increase proportional to the list size (IIRC it's about 12%, though there's some variance at smaller sizes). This does result in the same asymptotics though, so I'll assume doubling in the following description for simplicity. So basically it has to copy all addresses log(n) times. Not quite. Suppose we're appending n items to an empty vector. We will indeed do log(n) resizes, so you might think "Well, resizes are O(n), so log(n) resizes is n log(n) operations, which if we amortize over the n appends we did means n log(n)/n, or log(n) per append". However, there's a flaw in this analysis: we do not copy "all addresses" each of those times. Ie. the copies are not O(n). Sure, the last copy we do will involve copying n items, but the one before it only copied n/2, and so on. So we actually do 1 + 2 + 4 + ... + n copies, which sums to 2n-1. Divide that by n and you get ~2 operations per append - a constant. I assume since it copies addresses, not information We are indeed only copying the pointer, but this doesn't really matter for the complexity analysis. Even if it was copying a large structure, that'd only increase the time by a constant factor. Does that mean that O(1) is the average time complexity? It's the amortized worst case complexity (ie. what happens over a large number of operations). While any one operation can indeed end up doing O(n) operations, there's an important distinction that over a large number of operations, you are guaranteed to only be O(1), which is a distinction just talking about average case wouldn't capture.

If a container object’s __iter__() method is implemented as a generator, it will automatically return an iterator object (technically, a generator object) supplying the __iter__() and __next__() methods. More information about generators can be found in the documentation for the yield expression. There are three basic sequence types: lists...

You could create a list of the method names then use getattr() to access the methods:
instructions = ["shrink", "grow", "shrink"]
for i in instructions:
getattr(elephant, i)()

As an alternative to using strings for your list of instructions, you could do the following:
instructions = [someClass.shrink, someClass.grow, someClass.shrink,
someClass.shrink, someClass.grow, someClass.invert]
elephant = someClass(90)
sizeList = []
for ins in instructions:
ins(elephant)
sizeList.append(elephant.size)
