How do I get rid of the KeyError I get when I click scissor for a rock, paper, scissor game in Pytho-CodePudding

my code is running fine and all except for the time I click on scissors; rock and paper work fine without errors but I get a KeyError every time scissors is clicked. I'd appreciate some help given.

I'm making a rock, paper, scissor game if you haven't understood so far lol.

Actually though, my rock and paper work fine but I'm not sure why scissor gives me an error. I copy-pasted the code block for rock and paper yet scissor doesn't work. Honestly, I'm confused.

I think my dictionary went wrong but not sure. Please help.

outcomes = {
    "rock":{"rock":1,"paper":0,"scissors":2},
    "paper":{"rock":2,"paper":1,"scissors":0},
    "scissors":{"rock":0,"paper":2,"scissors":1}
}
comp_score = 0
player_score = 0

        return "rock"
    elif number == 2:

        return "scissors"

CodePudding user response：

outcome_handler("scissor") this should be scissors

CodePudding user response：

You have written ...lambda:outcome_handler("scissor")...

It should be ...lambda:outcome_handler("scissors")...
