As a recap,
0:00
a Python list is a way to store many
pieces of data in one container.
0:01
What kind of data?
0:05
Anything.
0:06
You can store any type of Python object in
a list, including integers, strings, and
0:07
even other lists.
0:12
Tuples offer the same functionality
with a slightly different syntax.
0:13
So what's the point?
0:17
Why have a tuple when you also have lists?
0:19
There are some semantic differences, but
the main difference is in mutability.
0:22
Lists are not static.
0:26
We can add elements to them and
remove elements from them.
0:28
This means lists are mutable.
0:31
In other words,
lists can be changed in place.
0:33
Tuples, however, are the opposite.
0:37
They're immutable, they cannot be changed.
0:39
Elements cannot be added,
removed, or reordered.
0:42
Mutability has different advantages and
disadvantages.
0:46
One is not better than the other.
0:49
They just have different use cases.
