未來簡單式

In this video, I'm gonna show you howto program Connect four in Python.

By the end of these videos, you have built something that looks like this.

It's a simple two player connect four game with graphics.

I think this is a really good exercise for your beginner to intermediate level python programmers who want to build their skills.

I'll just finish up a game real quick just so you can see how this fully works.

As you see I the diagonal and it's those player one wins school.

We're gonna do something a little bit simpler and then build up to that graphic based Connect four game.

Connect four game, where you actually mainly type in numbers to drop your pieces so you see the one there to cetera.

All right, so let's start building that just quickly.

I want to mention that I'll be programming and Python three and then using sublime text to is my editor.

I pushed a link to a video on how to set up these things in the description.

So one of the first questions I asked myself when I was writing this game is what is the best way to represent the board.

So by dragging a connect for Bordeaux quick, you can see that it is six rose by seven columns.

And to me, this looks like the perfect structure to represent as a matrix and python.

So to find a function called create board and that's not gonna accept any inputs, then we're gonna make a a matrix of all zeros with the Dimension six by seven.

And to help us do this, we're gonna import a package called Numb Pie.

And if you haven't already installed this, you can open up a terminal window and just type in pip install numb pie and, as you can see already have it.

So we're gonna use this as followers and say, board equals numb pi dot zeros.

And that's gonna make a matrix of all zeros, which is good for our initial state.

And then the dimensions six rose by seven columns.

And then we just need to return that board and we can test to make sure that worked by doing the following create board and then Prince board.

And as you can see if I don't know what happened.

As you can see, if I run that, um, we we do in fact, have this six by seven matrix of all zeros.

We can begin writing the mean game loop now.

So gonna raid a loop that says while not game over.

And so our life is gonna be running as long as this game over variable is false.

And the only way it becomes true is if someone has a foreign row.

So we need to initialize the game over to be false.

And the only way that's going to switch to true is if someone got a four in a row.

So now we're gonna need to We're also gonna want a real quick make our board initialized before we start the game.

Just so we have something to put pieces into.

So we have our board, we have a game over variable.

And now we're gonna want to be ableto ask player one input, and then we're gonna want to eventually be able to ask Ah, ask for player to input.

So this kind of leads us to the problem of Oh, how do we differentiate between whether it's player one or player two's turn, Israel's gonna define another variable appear called turn That's just going to initialize to zero.

So what we're going to say is, if turn equals, equals zero, then we're gonna wanna ask for player Want input?

All right, so in Python, there's a function of built in function called input.

As you can see, it highlights Pollux for May.

So we're gonna say selection equals input.

And then we're, say, player one, make your selection.

So this is what the player one's going to see, and then the way we're gonna initialize this game is we're going to just say they can type in between zero and six.

So this is what the player one should see.

So if I build this you see, we run to this error.

So this is because, um, sublime text doesn't accept this input function.

So my work around for this was I installed a package and sublime called Supply Mari pl I'll put a link in the description of how to install this, and I can run the input function through that.

So now you can see player one make your selection three, and it doesn't do anything with that input right now, but you can see that it's asking me that and I can type in enter.

So we also just want to make sure that it saves our selection properly.

So when a print selection, I also just want to see, you know, if I'd have been a number, does it actually give me the number?

Or does it give me a string that represents the numbers?

I mean, I also print in type of selection.

So I'm gonna run that again, as you can see ever again, but we're gonna go to supply Mari pl and the link is in the description, as I just said, Run current file.

So we're gonna want to make sure that it's actually a integer so we can just surround this with aunt input on this should work.

And you can also run this through the command line.

So if you run this in your terminal, go to the directory that the file is in and type in python and then file name.

Three cool and nice is it says three, and it says the class of that is an int.

So now you can save some sort of selection from the user.

And you can also edit this so that it, um, requires you to make a specific number, type in a specific number, but we'll just leave it as like, well, imagine our players air following the directions right now.

And then we're always gonna want to be able to ask for a player to his input.

Otherwise, if the turn is not equal to zero, um, then we want to ask for player.

Two inputs of selection equals it will just copied this from above.

And we'll just have the changes to say, player to make your selection.

And now, at the end of the turn, no matter whose turn it is, we're gonna want to increase.

So make it in committed by one and then we're also What we're gonna also want to do is we'll just make this odd Even so we're gonna use Ma division so it's gonna be turned mod to turn equals turn mod too.

And this is just basically making it go, uh, take the remainder of whatever our turn is divided by two.

So this is just gonna alternated between zero and one, so it will alternate between player one's tearing and player Tuesday.

So let's just see if this works properly.

So we're gonna run this build python current file player will make your selection to player to make your section for player one.

It's alternating between our player one our player toe Cool.

And now we're gonna want to start building our actual functionality.

You're gonna wanna be ableto make this selection right here.

So I want to find another function up here called definition drop piece, and we might to find a couple function, so maybe have ah drop piece and I'll just do pass for now.

Maybe we'll also have, like is valid location.
