00:00:00.000 --> 00:00:00.950
So, my first point is, an array's size is
immutable, you can't change it right?

2
00:00:00.950 --> 00:00:02.180
So you can't append, insert, or

3
00:00:02.180 --> 00:00:07.380
remove elements like you can with
a list and we showed that down here.

4
00:00:07.380 --> 00:00:10.400
All of an array's elements
must be of the same data type.

5
00:00:10.400 --> 00:00:13.350
I went and did a search for the different
data types that are available, and

6
00:00:13.350 --> 00:00:14.440
I made a little link here.

7
00:00:14.440 --> 00:00:15.910
I like to use those as bookmarks, and

8
00:00:15.910 --> 00:00:17.840
we'll actually use this
one here just in a bit.

9
00:00:17.840 --> 00:00:22.270
And then finally, a NumPy array
behaves in a Pythonic fashion.

10
00:00:22.270 --> 00:00:25.750
You can use len(my_array)
just like you'd assume.

11
00:00:25.750 --> 00:00:27.540
Awesome, how did you do?

12
00:00:27.540 --> 00:00:28.530
That feel good?

13
00:00:28.530 --> 00:00:29.610
All right, are you ready?

14
00:00:29.610 --> 00:00:30.000
Let's build out our study log.
