00:00:05,600 --> 00:00:10,420
In this section, we're going to be looking at some slightly more advanced Python features.

2
00:00:10,480 --> 00:00:15,450
Now we're going to start with generators which, as you see, are a great way to work with huge amounts

3
00:00:15,450 --> 00:00:16,610
of data.

4
00:00:16,680 --> 00:00:23,100
Now, another very useful feature in Python are comprehensions and we briefly mentioned earlier in the course.

5
00:00:23,580 --> 00:00:27,870
We're going to be having a look at what they have, and ways in which they can lead us to things that would

6
00:00:28,050 --> 00:00:30,950
ordinarily be difficult using a standard iterator.

7
00:00:31,230 --> 00:00:36,060
And the third thing we're going to be looking at in this section are lambdas, what they are and why Python

8
00:00:36,060 --> 00:00:39,050
still has them and alternatives to using them.

9
00:00:39,300 --> 00:00:40,370
So let's make a start.
