新的Python问题：获得TypeError：不可哈希类型：'list'

Question

所以我有一个课堂作业，我要做一个石头-布-剪刀的游戏，停止作弊。我一直在输入错误：不可损坏的类型：“list”

我不知道是什么原因造成的，有人能帮我解决这个问题吗？在

import random
import re

def MatchAssess(): 
    if userThrow == compThrow:
        print("Draw")
    elif userThrow == "r" and compThrow == "p":
        print("Computer chose paper; you chose rock - you lose")
    elif userThrow == "p" and compThrow == "s":
        print("Computer chose scissors; you chose paper - you lose!")
    elif userThrow == "r" and compThrow == "p":
        print("Computer chose paper; you chose rock - you lose!")
    elif userThrow == "s" and compThrow == "r":
        print("Computer chose rock; you chose scissors - you lose!")
    else:
        print("you win")



CompThrowSelection = ["r","p","s"]
ThrowRule = "[a-z]"

while True:
    compThrow = random.choice(CompThrowSelection)
    userThrow = input("Enter Rock [r] Paper [p] or Scissors [s]")
    if not re.match(CompThrowSelection,userThrow) and len(userThrow) > 1:
        MatchAssess()
    else:
        print("incorrect letter")
        userThrow = input("Enter Rock [r] Paper [p] or Scissors [s]")

Answer 1

应更正为

if  userThrow in CompThrowSelection and len(userThrow) == 1: # this checks user's input value is present in your list CompThrowSelection and check the length of input is 1
    MatchAssess()
