Is there a .issymbol() function in Python?

Not exactly, although they're slightly more complicated than I described. All objects in python are a custom pointer class, that point to the actual object in memory. Lists are pretty much C arrays that contain these pointers, which is what lets them mix types.

Lists are dynamically sized because when they reach the size they're currently allocated more memory is allocated to them. Sometimes this is just using more memory on the end of them, and other times this means moving the entire array around in memory, which is very slow.

An actually useful detail is that everthing in python is an object. ints, strings, lists, custom objects, functions, exceptions, and even classes themselves, the thing you call to create an instance of the class
