Chapter: Reading and writing files in Python
Lecture: Practice exercises
0:00 Well that's enough reading and writing files for me.
0:03 It's time for you to read and write to some files yourself.
0:06 So you're going to do some similar things
0:08 that we've done here, work with JSON files
0:09 work with lines of texts and plain text files.
0:12 Let's go see what I got on deck for you.
0:15 Over here in chapter nine working with files
0:17 you've got the standard introduction
0:19 threw in a few concepts for you, determining the full
0:21 path of a file using os.path, reading a file
0:24 using with open file name r, write in to a file
0:29 make it a w, working with a JSON, import this
0:34 loading from and writing to various files
0:36 and finally, the exercises that you're going to do
0:39 are going to be going back to the games that we created.
0:42 So, the Tic Tac Toe game from back in CH08
0:46 the one about problem solving at least
0:47 whatever number that turns out to be
0:49 at the end of this course, and work with that.
0:51 If you happen to have gotten all the way
0:52 through the previous chapters exercises
0:55 and you did build Connect Four, that one's yours.
0:58 Go ahead and use that instead.
0:59 The idea, we'll work with either of them.
1:01 What we are going to do is just create a leaderboard.
1:03 Use JSON format if you like.
1:05 That works out really easy so that's what we did.
1:07 So a leaderboard, create that, and update it
1:09 as you win and play.
1:11 Then add a running log file.
1:12 This can just be appending to a text file
1:14 nothing about it fancy, logging frameworks
1:16 and just do that.
1:17 That will help you practice appending to text files.
1:19 That'll be great.
1:20 If you want to, and you get to the end
1:23 and you want to try it out, you could use Logbook.
1:25 It's going to cover some of the topics we cover
1:26 in the external libraries package as well.
1:30 So, you don't have to do it now
1:31 but if you're feeling ambitious
1:33 feel free to go though their quick start
1:35 and give it a shot.
1:36 If it doesn't work, don't worry.
1:37 We'll talk about more of it for the next chapter.
1:39 But this is a really cool library
1:41 that helps you do logging the right way
1:43 and it's what we use
1:44 and it's been working great for years.
1:45 Alright, get out there and have some fun
1:48 adding file IL to the games that you built.
