Code a rock paper scissors game to play against computer AI with python! Great beginner project pt.2

hey what's going on you guys welcome back to the channel and welcome to part two of our uh creating a rock paper scissors game from scratch with python and if you missed part one i recommend you go and check that out essentially what we created was a format where you pick rp or s and then the computer picks rp or s just so you don't have to type in rock paper scissors every time and the computer's pick is randomly generated using the random integer function and then we process whether that would be a win loss or draw based on what you and the computer have picked so today we're going to look at some things that just make it a more fun game a more reusable code and this isn't just specific to rock paper scissors this is kind of a good practice thing to do for python so what we're going to do is we're going to create a game loop and basically anytime you're creating a reusable code you're going to want to do something along these lines so we'll say for this while play again does not equal no um and while play again does not equal no we'll run rock paper scissors but then what we need to do is we need to actually get the status of that play again variable from rock paper scissors so that we don't have an infinite game loop um but then let's go ahead and do also pass in this actually we don't need to pass it in we're going to get that back from them so uh what we want to do every time the game is finished so draw loss or win is we then want to create this like play again prompt and we want it to be an input where we ask the user would you uh let's just keep it short and say play again question mark and then let's tell them we would like to get back either yes or no okay and let's put that in uh all three scenarios and then let's go ahead and return once the loop is once the if statement has executed let's go ahead and return the play again prompt and so let's just run that and see if it lets us keep playing and no is not defined oh play again is not defined right yeah um so we'll just come up here in the beginning and we will create an empty string called play again so the initialize variable let's go and say rock we lost but we want to play again and let's do paper and we won and do we want to play again no i won okay so that exits the code that's cool um we just created replayability but then what else would be kind of nice in this function is if we also added some score tracking so there are basically three outcomes that could happen we could have wins um losses and draws or ties and so we'll just start out by making all three of those zeros but then every time we call this function to have those updated we have to pass in win loss and draw or we would have to make them global variables and then to update them in the outside world we're also going to have to make sure that we're updating them out here so let's go ahead and create them and losses draws create them everywhere and pay special attention to order because this does matter so for our rock paper scissors game now we are going to be passing in wins losses and draws and what's kind of nice is we already wrote the code in part one for tracking the scenario under which you would win or you would lose or tie so we'll go ahead and now we can just easily update the variables to add one to themselves every time something happens so here's losses add one to it and then here's wins add one to it so it's basically incrementing every time that scenario happens and then the last piece to make this really useful is going to be [Music] print a score prompt so let's go ahead and print and we'll say winds colon space and then we'll add the variable winds but that's going to be an integer so make sure you add the str function to make it a string and then we'll add another one and we'll start with a space and say losses colon space and then let's add the string version of losses and let's just do it one more time for draws and then we'll do we'll do the string of the variable draws and i'm just going to copy this exactly copy this and put it in all three places so hopefully every single iteration of this game loop as the score increments um we also see win-loss draw um going up draw is not defined because it needs to be blur alrighty let's try running that again all right let's pick rock and we tied okay but then we can see the score up updating so we picked paper oh i'm supposed to enter yes okay and now we pick paper and we won and let's play again and let's pick rock and let's play again and let's pick scissors okay well we can see our score and our losses uh counting up and counting up now let's say no we're done all right and we've exited um one thing i like to add to most of my functions especially for making a game or something that was supposed to be fun for the user i like to print a statement on the way out that just says like thanks for playing or something like that you know um and so this way after you play rock okay i won cool now i want to leave no you just leave him with a nice little message so this is pretty cool we just built a really fun replayable rock paper scissors against a computer like ai in just a few minutes and hopefully found this useful if you have any questions about this or anything you'd like to see next be sure to let me know about in the comments below i'll get back to you as soon as possible and if you found this or anything else on the channel useful i really appreciate a liking to subscribe it helps the channel out a ton as i'm getting started here and as always good luck with your code and thanks for watching thanks bye
