00:00:00,060 --> 00:00:02,370
Hey guys, welcome to day 35

2
00:00:02,400 --> 00:00:05,730
of 100 Days of Code. It's Angela here again

3
00:00:05,850 --> 00:00:09,000
and today we're going to be learning all about API keys,

4
00:00:09,240 --> 00:00:11,580
authentication, environment variables,

5
00:00:11,940 --> 00:00:15,690
and also how to send SMS using Python.

6
00:00:16,530 --> 00:00:20,190
It's going to be a pretty packed day and we're going to be learning a whole

7
00:00:20,190 --> 00:00:21,023
bunch of things.

8
00:00:21,360 --> 00:00:26,360
And the goal is the look at even more advanced ways of using APIs and

9
00:00:27,180 --> 00:00:31,710
looking at how we can authenticate ourselves with an API provider so that we can

10
00:00:31,710 --> 00:00:35,220
get access to more precious data. Now we're also going

11
00:00:35,220 --> 00:00:40,220
to be looking at how we can use an API like Twilio to send SMS messages to

12
00:00:41,370 --> 00:00:45,030
ourselves so that we can get an alert wherever we are.

13
00:00:45,750 --> 00:00:46,710
And finally,

14
00:00:46,740 --> 00:00:50,790
we're going to be taking a look at what environment variables are in association

15
00:00:50,790 --> 00:00:54,450
with how they're used for safely storing API keys.

16
00:00:55,140 --> 00:01:00,140
What all of this knowledge is going to amount to is to build a rain alert

17
00:01:00,750 --> 00:01:01,583
application.

18
00:01:01,950 --> 00:01:06,930
So we're going to be writing Python code that is going to send us a text message

19
00:01:06,990 --> 00:01:11,310
in the morning, just before we head out, telling us to bring an umbrella

20
00:01:11,580 --> 00:01:13,350
if it's going to rain in the day.

21
00:01:13,920 --> 00:01:15,960
So this way we don't have to check the weather.

22
00:01:16,320 --> 00:01:21,320
We know that our trusty application is always going to alert us via an SMS

23
00:01:21,420 --> 00:01:24,510
message if we need to bring an umbrella before we leave home.

24
00:01:25,140 --> 00:01:28,260
So that's the goal. And if you head over to the next lesson,

25
00:01:28,650 --> 00:01:33,570
we'll get started building our application and learning about API

26
00:01:33,570 --> 00:01:34,410
authentication.
