ワンライナーじゃんけんプログラム in Python

Last updated at Posted at 2022-11-23

入力

入力はGCP(グー、チョキ、パー)でおなしゃす

プログラム

結論から行くスタイル

import random; cpu=random.choice(["G","C","P"]); man=input(); print(f"{man} vs {cpu}"); gcp={'G':0,'C':1,'P':2}; result={0:"あいこ",1:"CPUの勝ち",2:"人の勝ち"}; print(result[(gcp[man]-gcp[cpu])%3])

必要最低限の解説

GCPを012にそれぞれ置き換えて、(man-cpu)%3を計算するとどちらが勝者か求まります

        %3  勝者
GG = 0   0  あいこ
GC = -1  2  man
GP = -2  1  cpu

CG = 1   1  cpu
CC = 0   0  あいこ
CP = -1  2  man

PG = 2   2  man
PC = 1   1  cpu
PP = 0   0  あいこ

余り2のときにmanが勝利
余り1のときにcpuが勝利

蛇足

ワンライナーとしては邪道かもしれない
