ChatGPT! I'm sure you've heard of it by now.
It can do a lot of awesome things such as answering questions, writing book reports, writing
awesome poems, and of course, it can code. So, I know a lot of people are scared that chat GPT is
going to take over coding completely and we're all gonna lose our jobs. This is horrible. I'm here
to say, calm down, it's not that bad. In fact, there are many ways chat GPT can help us become
better coders. That's why, in this video, I'm going to show you three ways that you can use chat
GPT right now to make yourself a better coder. Number one: adding comments to code. So, here I
have an example function where I'm given a file name, I open that file, and I print out each line
in that file until the end. Let's go over here to chatGPT and tell it: can you add comments to
this python code to make it more readable? Let's put things in triple quotes so it's
easier to know that this is a code block. And it's done giving the solution, let's copy
this over into my notebook. And you can see it's added comments to each line. There's a little
bit of over-commenting, and of course, it's up to you to double check the comments to make sure
they're right, but it can save you some time. Now, another way that this could also be
helpful is if you have a bunch of code that you don't understand how it works. You can
ask chat GPT to write the comments for you, and then it'll give you a better idea,
potentially, of how the code works. Number two: using chat GPT to make your
code easier to read. This is just a fake, complex function that has a lot of bad practices.
We see that we're checking A and B separately, and then we're also using this if return
and then if not return back to back. Let's give this to chat GPT and see if it can
make it more pythonic and easier to read. Here's the amazing thing about this: not
only did chat GPT give us a more pythonic, easier-to-read function, but it also listed
out all the changes it made and explained why that makes it more pythonic and easier
to read, all the way down to removing this one blank line in the code. Of course,
you need to know how your code works, so don't just rely on chat GPT to
do it for you, but in this example, it's clear that chat GPT was able to take this
simple function and make it more pythonic. The third thing I want to show you that chat
GPT can help you with is writing unit tests. This is something that many coders just avoid
doing altogether, but it's very good practice to write unit tests for your code. So, we
have an example class here called Rectangle, where we give it a height and width, and the
get_area method should multiply the height and width. We also have some setters here. So, let's
give this to chat GPT and see how well it does. And there we go! It's provided us a unit test for
this and also is explaining that the unit test covers these three methods for the Rectangle
class: get_area, set_width, and set_height. So, there you have three examples of how you
can use chat GPT to make your coding better.
