It's very likely you've got some kind of container for your data. That could be a list. We did a bunch with dictionaries just a bit ago.
0:07
Actually, dictionaries containing lists, how meta is that? it could be classes, and we also had classes in there.
0:14
So there's all kinds of different containers that we could use. But there's some that are interchangeable or somewhat replaceable.
0:20
I could have a list of numbers that, if a list just happens to have numbers, Python actually has array types, and
0:27
the more traditional, here's a big chunk of memory in the size of the object or the type of object is allocated and set just in line.
0:35
This only works for numbers, but that could be interesting. You could have Pandas or NumPy.
0:41
Maybe those things store stuff really efficiently or inefficiently. I don't know. We're gonna find out.
0:46
So what we're gonna do in this section as we're gonna look at a simple scenario, we're gonna have a bunch of names and bunch of ages
0:52
that correspond to those names. So basically details about people, and then we want to try to store them in different
0:59
things: lists, arrays, data frames and so on and just ask the question "if we start like this,
1:04
how much memory does it use?" versus "if it's stored like that,
1:07
How much does it use?" Because while certain containers might be more familiar and comfortable
1:12
Or maybe they have capabilities that we need or they're just the first thing that you think of, there might be a much better option in terms of memory
1:22
for what you're trying to do, and we're gonna sort of compare some of the common ones side by side coming up.
