Okay, so up until now, I have this question bugging me. I can't seem to understand about the practical difference between tuples and lists. Like, do they have an underlying structural difference or not, when I should use a tuple, and when I should use a list instead, that is, if I only have 2 items to store.

Question

So far the only difference that I have seen is , List are mutable and tuples are not..nothing more..
so in lists I  can change or delete a particular element but in tuples I can't..
But I am just on lecture 7..so there may be more to it..

Nah, I'm just a kind person :)

lists have a few more methods.  sometimes it is convenient to change a tuple to a list so you can use a list method to do something then turn it back into a tuple

anonymous · Answer

I don't know how you add something to a tuple ( there may be a way, I just don't know it).
on the other hand......list_name.append(thing you want to append).....

Well yeah, a tuple is immutable.... I suppose I gotta get that engraved in my mind.

The reason for the difference is that mutable objects are typically not hashable. As such, it's not reasonable to use a list as a key for a dict or store them in a set, but you can use a tuple for either.
